I don't know if this helps, but found Shockley when I was researching my Adams line.In Marlboro Co. SC Wm. b.1740 m Obedience & when he dies she M. Luke Robeson.. in her will she names step sons.. Wm. Adams, John Adams, Shockley.This was in 1812.
I also know that a Richard Adams m. Amy Shockley.. they were in Lunneburg Co. Va. 1749-1750.
Wm. Adams and Obedience have a daughter too..Divinity Shockley isn't a real common name so this has to be yours somehow. good luck
