In 1930 Wesley b. 1886 in Mississippi and Cornelia b. 1894 in Virginia, Bailey living in Fairmount Heights, Prince Georges County, Maryland (DC suburb). At the time they had two children, Evelyn age 4 and Janet age 1.
Around 1942 his address was 112 Clark Avenue, Fairmount Heights, Maryland, and listed Cleona Scott as a person that would always know his address. He owned his own business as a brick layer.
Then Wesley born November 19, 1885, died in Washington, DC in June, 1968. Cornelia Bailey born December 27, 1893, died in Washington, DC in September 23, 1989.
I found a current address for Ada Bailey in DC, several Mary Barnwell, one Florence Bailey, lots of Barbara and William Bailey. However, the sisters may have married and without more information it would be difficult to determine if they are the relatives you are trying to find, since their first and surname Bailey are very common names. If you are interested in the names I have found, email me direct and I will send them to you. firstname.lastname@example.org
