I'm now wondering if the "Cowsa" name I gave might have been Cowan...?
Ref to this thread:
2nd post refs the 1841 census for Riccarton, and in the household there is "Margaret Cowan female 1 b Ayrshire"
I also believe it would be a good bet the father of John McKelvie (m. Agnes Muir McKelvie) would likely have been named "Francis." - He's married to this Cowan/Cowsa.
In turn, I'm thinking, this Francis' father and mother may have been the John & Janet (Buntine) McKelvie's of Dundonald, Scotland.
And in step with the 1st born son named after every other generation, my grandfather (J.Ward MacKelvie b. 1890, youngest of 5) - his oldest brother is John Robert McKelvie.
So, looking at 1st sons born going backwards:
John Robert McKelvie b.1876-1948
Francis McKelvie b. Ayr ~ 1840-1891
John (& Agnes) McKelvie b. Riccarton 1807-?
(possible) Francis (& ? Cowan/Cowsa) McKelvie b. Dundonald 1779
(possible) John (Janet Buntine) McKelvie of Dundonald(?), Scotland.
I still can't figure out if Thomas (Janet Muir) and John (Agnes Muir) were brothers though. I suspect there may have been more children of the John (Janet Buntine) McKelvie's and they maybe were cousins instead.
