Origins

What evidence supports as son of Samuel Gallup & Mary Gallup ?

From https://www.wikitree.com/g2g/559539/did-pgmer-samuel-gallop-have-so...

According to his profile, Robert Gallop, Gallop-1 was the son of Samuel Gallop and his wife Mary Phillips Gallop of Boston. I have found the baptism for their son Samuel, but no other children
In 1698 a man named Henry Gallop/Gollop bought a piece of land in Richmond County, Virginia, from John Owens and his wife, Rebecca. Robert Gollop witnessed the transcaction. There is no information to show where Henry and Robert originated. [Richmond County VA Deed abstracts, 1695-1701]
Robert Gollop died in 1720; his will was proved 7 Dec 1720 by his widow, Eleanor, who brought along three friends: Henry Gollop, Richard Elkins, and William Brown. They all confirmed that although Robert left no will, he stated with his dying breath that he wanted his land “at Deep Run in this county” to be equally divided between two of his daughters, Eleanor and [Phyllis?]. [Robert had two other daughters: Mary, who was married to Richard Elkins, and Ann, who was married to a Robert Duncan.] [Wills of Richmond County, Virginia 1699-1800]
Rebecca Owens had apparently died by this time, because John Owens and Eleanor Gallop then married.
Henry Gallop died in 1726 and left his property to his four nieces (called cousins in the will):
