Since writing I have been able to confirm the William Lewis in my tree is not the same one as yours. Mine was born William Thomas and seen as a relative in 1851. By 1861 he is a son so probably adopted into family. This one eventually marries in Salford and states Titus deceased coachman to be his father. Titus Lewis must be related to your william further back. Kenarth was a small place and there weren't many families there. If you find a link to my Titus who married Rachel Thomas I would like to know.
