From Byron Deveson.
It is interesting that Clive sees a resemblance to SM in the Scots-Irish actor Stephen Boyd (AKA Millar) because SM’s mtDNA haplogroup is present at significant levels in Ireland. See:
It appears that Scots-Irish were mercenaries in Finland in the 16th Century and that could explain the high incidence of the H4 haplogroup in Finland (and Iceland where it constitutes 9%?).
I am reminded that there was a large “tartan” scarf (shawl?) in SM’s suitcase. From memory the tartan looked like a military or an Irish tartan. Or even a Norwegian tartan. But the pattern is oblong and all genuine tartans appear to be square as a consequence of the weaving method.
Tweeds are often rectangular and SM’s “tartan” scarf appears to be a tweed, not a tartan. Unfortunately tweed patterns and colour were chosen for camouflage (hunting) and this is consistent with the appearance of the scarf/shawl in the black and white press photo.
Tweeds are often dun coloured to fit in with the Scottish landscape. A dark blue and green tweed such as the one from SM’s suitcase would be an exception from my vague memory of such things and this might be an overlooked clue. Dark green and blue suggests deep forest to me and, relying on dim memory, these are not abundant in Scotland or Ireland. I note that some estates had their own tweed pattern and some estates had private forests. The possible US belongings (comb, lighter and coat and chewing gum(?) from memory) bolster the case for SM being American and Scots-Irish DNA is concordant with US East Coast heritage.
I started building a family tree commencing with Robin Thomson’s likely forbears Tarleton Pleasants (1778-1836) and Tabitha nee Crew (1788-1819) but I found so much contradictory information that I gave up.
I started by assembling all the available material, regardless of the contradictions, with the intention of straightening it all out. But, I soon found that the descendants of this couple could not agree as to whom begat whom and when, so I didn’t stand a chance.
I pushed on in the hope that one of the descendant lines would show some connection to Australia, and some do. The Merryman family comes to mind. But, nothing crystallised and I decided that there was more than a thousand hours of research required and only a relatively small chance of success. So, there the Pleasants family tree rests.
