I can only go back as far as John Callen born unknown date in ireland. he had 2 sons, Patrick and William Sr ( born 12 may 1735 in Landcaster PA). William had 4 sons Thomas(born 20 Mar. 1762), John (born in 1765 Mecklingburg NC), James (born 1770 in Cabarrus NC), and William Jr. born about 1772. Thomas was my great great grandfather i believe. I have some family documents but would love to learn more about John in particular.If anyone has gone back farther i would appreciate any info. Has anyone seen, or read the Callen Chronicals? I would like to obtain a copy
