I've been looking through my notes and found other information--William Pinkney Sr and Earlena Coggins had the following named children...

Robert Bn 1912 SC
William Henry bn 1914 SC
Ethel bn 1917 SC. (married name Walker) lived in Fulton Ga in 1961
Lucille bn 1919 SC(married name Richardson)

Earlena Coggins had sisters, From Cleveland Ohio...

Cora Black
sis-Willie Perdue
Sarah McCland
Martha Briley
Blanch Camp
Eula Sewell
Brother..
J. E GEORGE of Detroit, Mich

The siblings names were found on a obiturary notice for Earlena. Funeral services were conducted at New Hope Baptist Church, in Merriweather, Ga. Rev. G H Henry was the pastor, Rev. JB Street Minister. Earlena was buried Aug 1961 at Lincoln Memorial Cemetery in Atlanta, Ga.
This obit information was in the Atlanta Daily World

I am hoping by giving this information maybe Earlena's sisters family, may know of descendants of the Pinkney's and they will contact me through this Posting.

You know in doing this research, I know of family now living in Detroit, from other branches of my family. To preserve privacy I will give the ancestors surnames and not the cousins present surname.
Adams descendants that migrated from Aberdeen, Ms.
White surname descendants, that migrated from Tennessee.
You just never know who you may living next door to or even working with.
