A special election was held in Maryland's 7th congressional district to fill a vacancy left by the resignation of John Brown (DR) to accept a position as clerk of the county court of Queen Anne's County.
[1] Brown had earlier been re-elected to the 12th Congress, thus, his resignation created vacancies in both the 11th and 12th Congresses.
Unusually, a single ballot was used for both vacancies.
This was the first of at least three examples of this sort of dual-vacancy being filled with one ballot.
[2] Robert Wright took his seat December 3, 1810[1] at the start of the Third Session of the 11th Congress.
