Did you ever find the info you needed about John Albritton. If so, I would be interested in what you found out.If you are still looking, I may have info for you.
I suspect the John Albritton you are seeking info on is in my lineage. I show a John Thomas Albritton, b. 2 Dec 1823 in Pitt Co., NC.His parents are Luke Albritton, Jr. and Elizabeth Atkinson, who lived in Pitt Co., NC, then moved to Graves Co., KY in 1832.Luke's parents were Luke Albritton, Sr. and Betsy Albritton (believed to be an aunt of Elizabeth Atkinson). Luke, Sr. was a son of Peter Albritton, b. 1742.I have no further data on John Thomas (b. 1823) so I would interested in knowing if this is the one who married your gggrandmother.
