There are 4 possible baptism around the time:
1. to John & Esther Watterson 18 Apr 1824 at St George, Douglas
2. to Robert & Ann Corlett 12 Oct 1828 at Lezayre
3. to William & Elizabetb Crennel 18 Jan 1830 at Ramsey
4. to William Kewish & Elizabeth Starkey 6 Oct 1833 at German.
1 does not appear in the 1841 or 1851 census but John seems to be in the 1861 census, a widower, and his birth place is given as St. Johns, NB.
2 & 3 appear in the 1841 census.
I cannot identify 4 in the 1841 census.
