Searching for the birth parents of Irving and Exer Ornsby, who were brother and sister around 1905. They were "adopted" by the Strong family. From what I've learned, the Strong family was related to the Ornsby's somehow. And for some reason, the Strong family ended up taking full custody of Irving and Exer Ornsby, who's names eventually changed to Irving & Exer Strong.
Exer Strong kept this surname until her death in the 1990's. Irving changed his name to Irving Williams, when he left Hogansville, GA and moved to Detroit, MI. He passed in 1990.
If you have any information, that would be a great help in linking this family.
