Hi Bruce I see you have lumped the Dunn children born of James Dunn and Thomazine Broom in Devon with the four born of James Dunn and Thomason Strachan born in Oak Hill and Wigtown.. I have also considered these two groups of children several times. First of all it is true that there seems to be no direct conflict in dates (assuming Jean was born about 1806) - ie the Devon children fill a large gap between John born 1793 and Jean born 1806. However, there is a marriage in Burlescombe, Devon of James Dunn and Thomazine Broom in 1795 (Family Search M16848-2) and the children are born 1795-1805 which seems consistent. There also appear to be numerous census reference to these Dunn children born in Burlescombe in English censuses but no reference at all in Wigtown censuses. Another option might be for the first Thomason to die in 1793/94 and James to marry in Devon in 1795 - however, if that was the case, they then returned to Wigtown without any of the children and the death report for Thomason 1809 stated that her mother was Thomson Strachan. So I have to conclude that these two families were separate. The bigger mystery, I think, is what happened with James and Thomason in that 13 year gap from 1793 till 1806 or so? Did they have a number of still births? Were they living in Wigtown or in Oak Hill? (was it Oak Hill London or Somerset?) The fact that both the wife and one child were born in Oak Hill, England seems to indicate that James was moving back and forth between these two locations at least twice, for employment, I assume. Any Idea why Oak Hill? Blessings John in Canada
