Easy answer--the Boone Society does not accept it. They want more information.
Sarah Boone married Jacob Stover Sr. in 1715. By 1738 he was married Margaret. It is not known when Sarah died or when he married Margaret, so it's not clear which woman was the mother of his children.
Quoting from The First 5 Generations of the George Boone Family
Presented by The Boone Society, Inc., Updated August 2012:
"Sarah [Boone] married Jacob Stover 15 March 1715 in Pennsylvania, Hazel Spraker, The Boone Family p. 23.
"No known children of Sarah Boone & Jacob Stover, explains Spraker, Sarah married Jacob Stover 15 Mar 1715, as recorded in Christ Church, Philadelphia ... possible that she died quite young, and her descendants, if any, are unknown. While she was the first in the family to settle in in the Oley Township, she evidently did not affiliate with the Friends Meeting there, as no data concerning her appears in Quaker records. She was no doubt absorbed by the German element into which she married ... In 1738 a wife Margaret (Stover) signed a deed for land sold by Jacob to another person, so Margaret was probably a second wife.
"(Some researchers believe there were children of this marriage, or at least of Stover's second marriage. Proof sources here would be welcomed.)"
