Ladies and Gentlemen:

         This letter is in reference to the Registration Statement on Form SB-2,
as amended,  (the  "Registration  Statement")  filed by  Mid-Atlantic  Community
BankGroup,  Inc.(the "Company") with the Securities and Exchange Commission (the
"Commission") for the registration  under the Securities Act of 1933, as amended
(the "Act"),  of 149,500 shares of the Company's  common stock,  par value $5.00
per share (the "Common  Stock"),  which shares are proposed to be offered to the
public  pursuant  to an  Underwriting  Agreement  filed  as an  exhibit  to  the
Registration Statement (the "Offering").

         We have examined such corporate  proceedings,  records and documents as
we considered necessary for the purposes of this opinion.

         The  opinion  expressed  herein  is  limited  in  all  respects  to the
application of the law of the Commonwealth of Virginia.

         Based  on  the   foregoing,   and  subject  to  the   limitations   and
qualifications  set forth  herein,  it is our  opinion  that the  aforementioned
shares of Common Stock,  when issued against  payment  therefor  pursuant to the
Offering,  will be validly issued,  fully paid and non-assessable under the laws
of the Commonwealth of Virginia.

         Our opinion is expressed as of the date that shares of Common Stock are
issued pursuant to the Offering against payment  therefor,  and we do not assume
any  obligation  to update or  supplement  our  opinion to  reflect  any fact or
circumstance  subsequently  arising or any change in law subsequently  occurring
after  such date.  We hereby  consent  to the  filing of this  opinion  with the
Commission as an exhibit to the  Registration  Statement and to the reference to
us under the caption "Legal  Opinions" in the  Prospectus  forming a part of the
Registration Statement.


                                       Very truly yours,

                                       WILLIAMS, MULLEN, CHRISTIAN & DOBBINS
