Debbie,
I'd be interested in what conclusions you come to.

I had assigned Ann CALLOW as daughter of Thomas CALLOW & Ann KERRUISH, from my Balldromma Beg line. This is them in:

1841 Census: Thomas, 45 (sic), Ag Lab, is living at the Barrony, Maughold, IOM, with his wife Ann (43), and children William (15), Margaret (14), Ann (9), and Daniel (3).
1851 Census: Thomas (aged 53yrs) and wife Ann (53yrs) on 12 acre farmlet at "Howe", Maughold, with son Daniel (12 yrs).
1861 Census: Aged 63, Ballaskeig beg, Maughold.
1 51 Cottage on Ballaskeg beg Thomas CALLOW Head MAR 63 Ag lab Maughold
1 51 Cottage on Ballaskeg beg Ann CALLOW Wife MAR 63 Maughold
1863: "Labourer"
Res: Ballaskeig-beg, Maughold (1873)
