Henry A Swink's father?

I am also a descendant of Henry Alexander Swink (b. 1813 in NC), through Amelius Davenport Swink.Most of the records I've seen stop with Henry Alexander.Does anyone know who his parents were?Forgive me if this has already been posted -- I'm new to the forum.Also, my mother's records says Henry Alexander Swink died Jan. 25, 1879 in Grayson...can anyone confirm which state this Grayson would be in?I find a Grayson County in Texas and one in Kentucky, but I'm assuming it's the former since Amelius raised his family here in TX.

Thanks for any help!
