Sorry Sally, I've looked around and can't find very much of anything.

In 1841 there is a Charles Kinley age 15 Baker Ap at Arbory Street, Malew, at home of Robert Clague 30 Baker. I can't find him after that.

In 1841 there is an Elizabeth Kinley age 15 F.S. [for "Female Servant"] at Harris Terrace N No 9, Onchan, at home of Mary Buckley or Anne Winterbottom. Nothing more after that, though she could have married.

Nothing for son Thomas at all.

Age "15" is actually anything from 19 to 15.
