                          _____________, 199_


Farmers National Bancorp
5 Church Circle
Annapolis, Maryland 21401


Ladies and Gentlemen:

      We have acted as tax counsel to you in connection with the merger
(the  "Merger") of Farmers  National Bancorp  ("Bancorp") with  and into
First  Virginia Banks,  Inc. ("First Virginia") pursuant to  and in
accordance with  the terms and conditions of  the Agreement and Plan of
Reorganization dated as of July 1, 1994 between Bancorp and First
Virginia and the  Plan  of  Merger  dated  as of  July  1,  1994
between  Bancorp  and First  Virginia (collectively,  the "Affiliation
Agreement").   Pursuant to the  Affiliation Agreement, on the Effective
Date  (as that term is defined in the Affiliation Agreement) the Merger
will be consummated.   You have requested  our opinion regarding certain
of  the federal income tax consequences of the Merger.

      All  capitalized  terms  used  in this  letter  without
definition  shall  have the respective meanings specified in the
Affiliation Agreement.

      In rendering the opinions expressed in this letter, we have
examined and relied upon such documents as we have deemed appropriate,
including the Affiliation Agreement.

      In  our  examination of  documents, we  have assumed,  with  your
consent,  that all documents submitted to us as photocopies or by
telecopy faithfully reproduce the originals thereof, that  all original
documents  are authentic, that  all documents submitted  to us have been
duly  executed and validly signed by all parties  thereto to the extent
required in substantially the same  form as they have been  provided to
us, that all  signatures on all documents submitted  to us are genuine,
that all natural persons who  executed any of the documents submitted
to us had,  at the time of  execution, legal capacity,  that each
executed document constitutes the  legal, valid, binding and enforceable
agreement of the signatory parties, that all representations and
statements set forth in such documents are and will  remain true,
correct, and  complete, and that  all obligations  imposed on  the
parties by any of the documents have been or  will be performed or
satisfied in accordance with their  terms.   We have  further assumed
that you have  disclosed to  us all  of the documents that are relevant
to the transactions that are the subject of this opinion.

      We also have  obtained such  additional information and
representations as we  have deemed  relevant  and necessary  through
consultations  with various  representatives  of Bancorp and First
Virginia.  Likewise, we have obtained a written certificate from certain
officers of Bancorp  to verify certain relevant facts that have  been
represented to us or that we have been authorized to assume in rendering
this opinion.

      Based upon the aforementioned  consultations and certificates, we
have  assumed with your authorization that the following representations
are true on the date hereof and will be true on the Effective Date.


      1.    Bancorp will  pay its own  expenses, if any,  incurred in
connection  with the Merger.

      2.    The fair  market value  of the  consideration to be
received by  each Bancorp shareholder in  the Merger will  be
approximately  equal to the  fair market value  of the Bancorp Common
Stock surrendered in the exchange.

      3.    There is no  person who  is the beneficial  owner of five
percent or more  of Bancorp Common Stock.

      4.    The management of Bancorp is not aware of any present plan
or intention on the part of the  Bancorp shareholders to sell,
exchange, or otherwise dispose of  a number of shares of First Virginia
Common Stock received in the Merger that would reduce the Bancorp
shareholders' ownership  of First  Virginia Common Stock  to a number
of shares  having a value, as of  the date of the Merger, of  less than
50 percent of the value  of all of the formerly outstanding Common Stock
of Bancorp as of the  same date.  For purposes  of this representation,
shares of Bancorp Common Stock to be exchanged for cash are assumed  to
be outstanding shares of Bancorp Common Stock as  of the date of the
transaction.   Moreover, shares of Bancorp Common  Stock and shares of
First Virginia Common  Stock held by Bancorp shareholders and otherwise
sold, redeemed or disposed of prior or subsequent to the Merger were
taken into account for purposes of this representation.

      5.    The liabilities of Bancorp and the liabilities to which its
assets are subject as of the Effective Date were incurred by Bancorp in
the ordinary course of business.

      6.    There is  no intercorporate  indebtedness existing between
Bancorp and  First Virginia that was issued, acquired or will be settled
at a discount.

      7.    On the date of the Merger, the fair market value of the
assets of Bancorp will exceed the sum  of its liabilities and  the
liabilities, if any,  to which its assets  are subject.

      8.    On the date of  the Merger, the basis of  the assets of
Bancorp will  equal or exceed  the sum of its  liabilities and the
liabilities, if any, to  which its assets are subject.

      9.    None of  the compensation received by  any shareholder -
employees of Bancorp will be separate consideration for, or allocable
to, any of their shares of Bancorp Common Stock; and the aforementioned
compensation will be for services actually rendered and will be
commensurate with  amounts paid to third parties bargaining  at
arms-length for similar services.

      10.   First Virginia has no present  plan or intention to sell or
dispose any of the assets of Bancorp or its Subsidiaries on or after the
Effective Date of the Merger, except for (i) sales,  transfers or other
distributions  made in the ordinary  course of business and (ii)
transfers described in Section 368(a)(2)(C) of the Internal Revenue Code
of 1986, as amended (the "Code"); First Virginia has  no present plan or
intention to reacquire any of the shares  of First Virginia  Common
Stock it  will issue  to shareholders of  Bancorp pursuant to  the
Merger; and  following the Effective  Date of the  Merger, First
Virginia will  continue the  historic  businesses  of Bancorp  and  its
Subsidiaries as  presently conducted.

We have  undertaken no  independent investigation  or  verification with
respect to  such representations or any other factual matters on which
our opinion is based.

      Based upon the foregoing and the representations  set forth above,
it is our opinion that:

      1.    The  Merger will  constitute a  reorganization within  the
meaning  of Section 368(a)(1)(A) of  the  Code.   Bancorp  and First
Virginia  will each  be  "a party  to  a reorganization" within the
meaning of Section 368(b) of the Code.

      2.    No gain  or loss  will be  recognized by  Bancorp or First
Virginia upon  the transfer  of all of  Bancorp's assets  to First
Virginia pursuant to  the Merger  and the assumption of the liabilities
of Bancorp by First Virginia pursuant to the Merger, or upon the
distribution to Bancorp shareholders  of the consideration to  be
received by them in the Merger.

      3.    No gain or loss will  be recognized by Bancorp shareholders
upon  the exchange of their Bancorp Common Stock solely for First
Virginia Common Stock.

      4.    The gain,  if any, realized  by a  Bancorp shareholder upon
receipt of  First Virginia Common Stock and/or cash  in the Merger will
be recognized, but in  an amount not in excess of the  cash received.
No loss  will be recognized by Bancorp  shareholders who receive  only
First  Virginia Common Stock  in the  Merger in  exchange for  their
Bancorp Common Stock.

      5.    The  basis of  the First  Virginia Common Stock  received in
the Merger  by a Bancorp shareholder will  be, in each instance, the
same as  the basis of such shareholder in the Bancorp Common Stock
exchanged therefor.

      6.    The holding  period of  the First Virginia  Common Stock to
be received  by a Bancorp shareholder in  the Merger will include, in
each instance, the holding  period of such shareholder in the Bancorp
Common Stock exchanged therefor, provided that the Bancorp Common Stock
is held by such shareholder as a capital asset on the Effective Date.

      Our  opinion is limited  to the federal  income tax matters
specifically covered by this letter, and we  have not been asked to
address, nor have  we addressed, any other tax consequences of the
Merger.  Without limiting the generality of the foregoing, no opinion is
expressed with respect to the tax consequences of the Merger under other
provisions of the  Code  and regulations  thereunder or  with  respect
to  the tax  consequences  of any conditions existing  at the Effective
Date of, or  effects resulting from, the Merger that are not
specifically addressed in  this letter.   Further, no  opinion is
expressed  with regard to  the tax consequences  of the  Merger under
applicable  foreign, state  or local laws.

      The  opinions expressed  herein are  based solely  upon the
documents that  we have examined, the additional  information that we
have  obtained, and the  representations set forth above  that we  have
assumed to  be accurate  as of  the date of  this letter.   Our opinion
cannot be relied upon if  any of the facts contained  in such documents
or in  any such  additional  information  are,  or  later   become,
inaccurate  or  if  any  of  the representations  set  forth above  are,
or  later become,  inaccurate.   In  addition, our opinion is based upon
existing law and current applicable rules,  regulations, rulings and
court decisions  in effect  as of the  date of this  letter, all  of
which are  subject to change at any time either prospectively or with
retroactive effect.  Any such change could modify or adversely affect
our opinions  set forth herein.  We undertake no  obligation to update
or modify  our opinions or this letter with respect  to any changes in
or affecting the Merger or any  of the foregoing which  may occur after
the  date of this letter.   The opinions set forth in  this letter have
been expressed solely for the  use of the Board of Directors and
shareholders of Bancorp, and may only be relied upon by them.   Our
opinions in this letter are not to  be quoted in whole or in part or
otherwise referred to without our prior written consent.

      We hereby consent  to the filing of this  opinion as an exhibit to
the Registration Statement on Form S-4 of First Virginia  for the
registration of 4,048,584 shares of First Virginia Common Stock under
the Securities Act of 1933, as amended (the "Act"), and to the
references to us  in the related Proxy Statement-Prospectus under  the
captions "SUMMARY - Certain Federal Income  Tax Consequences," "THE
AFFILIATION - Certain Federal  Income Tax Consequences" and "LEGAL
MATTERS."  In giving our consent, we do not thereby admit that we are in
the category of persons whose consent is required under Section 7 of the
Act or the rules and regulations of the Securities and Exchange
Commission thereunder.
