I Can Trace Back to My Great Grandfather Albert a

I can trace back to my great grandfather Albert A. Thompson, born 10-1-1877 and died 6-10-1933. He had 3 Children, Mable C. (b 4-14-1900-d. 6-2-1901): Lucian A.(b.3-27-1902-d.8-11-1925): My grandfather Luther J. Sr.(b. 12-22-1904-d.2-12-1992) I am looking for all ancestors before Albert A., and the lost child of Lucian. Lucian committed suicide after discovering that his girlfriend moved to Waco, Tx. from Mexia, Tx. to hide her pregnancy.
