DC Tuckers, mid 19th century
I don't know much about my Tuckers yet, but I'm afraid I don't have a William Tucker. My bunch seems to go Henry Tucker (b. abt 1806), married Ellen Lanham, had 5 children between 1823-1841 including Mary Elizabeth, Ann Josephine and Joseph A. Tucker. They were from Georgetown DC, and seem to have been Catholics.
There's a William listed in the 1850 DC directory as a tobacconist with a shop on 6th street NW and a home on C street NW....
Have you tried getting the records from Congressional Cem.?
