There is a baptism entry for a Humphrey Jones in Llangollen in 1813, son of Thomas and Elizabeth. Also a marriage for a Humphrey Jones and a Sarah Jones in 1831 in Pontfadog. The 1841 census shows a Humphrey and Sarra? Jones in Llangollen with a Thomas, 1836, Mary Ann,1839 and Elizabeth, 1840.
I hope this helps
