Several years ago I did a thorough review of Deeds from Hopkins County Texas. Deeds are supportive of David Nickless being a child of Josiah Smith Stockton as Josiah's land was partitioned among his children, including David Nickless. The details are too exhaustive to be included in this paragraph.

Josiah Con Stockton married Martha Adeline Walker in Denton County, TX per her application for civil war widow's pension.
