Sextons descended from Michael Sexton c1810-?? (Toehead)

Unfortunately, very little is known about Michael Sexton (G3) who was born in about 1810 other than that he was married to Catherine (nee Hourihan) and that he leased land in Toehead. We do know, however, that he had at least one child, Timothy (G4) who was born in 1853. It is not known when or where Timothy died but it would appear that he either died before marrying or else emigrated as a young unmarried man.
