Re: WASHINGTON DC Mullen Families;William S.
William S. Mullen had three wives and about 11 children in DC: William Marcellus (b.1845), Arthelia (1848), Mary Elizabeth Gabriella(1852), Emma Jennette "Kate" (1854), Mary Jane (1859), Henry Joseph (1861), Annie (1866), Eva and Sarah"Fannie" (twins 1869), and Maud (1872), plus one or more infants who died!
Another researcher I know is working on the William H. Mullen lines in DC.
I only have your Dewitt C. Mullen in my notes from the 1920 census soundex. Can you tell me more about your line?
