If you're still looking, from what I have pieced together, sons Joseph K. and Martin K. moved to Caldwell Countyy, KY prior to 1840. Joseph K. later purchased land and moved to Lyon Countyy, KY. Best I can figure, Martin K. (my gggGrandfather) remained in Caldwell Countyy. It's possible they took their father Joseph or their father took them from North Carolina to Kentucky or they moved as a family group. Best guess I would start in Caldwell Coo around Princeton unless you know the exact location of the Graveyard. There are quite a few Asbridge's in KY that may be decended from the same family.

Let me know if your search is fruitful, haven't made it up there as yet.

Do you have a location on the cemetary you mentioned?

I'm suspicious that someone may have gotten the son & father confused and Joseph & Sarah remained in North Carolinaa.

Good Luck and Good Hunting
