Ross was the son of Thomas J. Adams and Mary E. Thompson. He was probably born in or near Elkton in Todd Co., Kentucky.
He married Dora Unknown, possibly in Kentucky as no marriage record has been found in Missouri. Ross and Dora had two children; an unnamed son, and daughter Vhey Willie who married Edger Ernest Mueller.
No death certificate or burial record for Ross Adams has been found in Missouri. Vhey and Edgar Mueller were living in Okmulgee, Oklahoma by 1930, perhaps he was with them at the time of his death.
