your suggested Wm was the 2nd son of a successful [house]painter on North Quay
- however he is missing from 1851 + 1861 censuses but I can't see any burial
- tho the parents of illegitimate children should be presented for fornication (and were in the more rural parishes) by this period Braddan wch included Douglas no longer bothered
you need to find the marriage record Kerr is a fairly unusual name on Island wch should name his father
(Quay is a possible alternative spelling)
