Andrew,
Thanks for your response. It has made us review some of our information as, whilst possible, it didn't seem correct that James(b1787) would be having a second marriage in 1841 to Ann Jackson(b1816). You would expect that Ann would be marrying someone in their 20's but we have not been able to find a record of a Whitehaven birth for a James Callow around the right time - c1810-20.

However, if James Callow & Jane Quine who married in IOM around 1812 (ref: George Callow Canada)had James in the IOM as an older child before William, Ann & Thomas then we have been looking in the wrong place. The son James apparently doesn't appear in the Whitehaven household of James & Jane in the 1841 census only William, Ann & Thomas (ref: Isobelruss - Rootschat.com 16Mar07). However, as a mariner James jnr could have been away at sea or elsewhere as he would be aged 20+ at this stage and hasn't featured in the census. We do know from the marriage certificate of James Callow and Ann Jackson in June 1841, both of "full age", that one of the witnesses was a William Callow who could have been his brother (and the ancestor of your wife?).

In summary, we are probably now looking for a James Callow, born before 1820 in the IOM to James Callow & Jane Quine. It is also conceivable that as this birth is up to 8 years after their marriage then there might be other IOM Children born before they moved to Whitehaven - on the other hand James may just have been away at sea an awful lot during the first years of the marriage!

Would be glad to receive any thoughts on this. In looking for some of this information we have come across some other details of William & his descendents through his eldest son Joseph that may help fill any gaps you have.

Regards,

Bruce Callow
