I just came across this post. You may already have the answer for this. My great grandfather was Bert Thomas Stinson. His father was William Harvey Stinson (1859-1912) who was the son of Elijah Stinson.
His children with Kate Brandon were Fred Thomas, Hallie Clay, James Whit, William Guy and Mary Catherine.
His children with Bertie Lundy were Mabel Irene, Ernest Dearl, Bert Thomas Jr, Billy Edward, Marjorie Sue, Mary Francis and Shirley Ann.
Hope this helps.
