James Carmichael Smyth was apparently a Royal physician at the end of the 18th century; he married Mary Holyland, and it's Mary that I'm trying to trace.
According to the Peerage, Mary was the daughter of Thomas Holyland of Bromley and Mary Elton, married James in Gretna Green in 1775, and died in May 1806. Here's that link:

https://www.nationalgalleries.org/art-and-artists/129202/mrs-james-carmichael-smyth-died-1803Mary's mother left a will which was proved in 1783, when she (Mum) was living in Westrop, Buckinghamshire. Mary's mother had been widowed and remarried Thomas Wilkinson; the only child she mentions in the will was her daughter Mary, wife of Dr James Carmichael Smyth (so I know this is the correct Mary). She also mentions her sister Elizabeth Elton, which ties in with her having been Mary Elton when she married Mary's Holyland father.
And this is where it comes a bit unstuck. Holyland-Elton marriages are not exactly common. I cannot find a Thomas Holyland of Bromley, despite what the peerage page says. I do however have a marriage between Christopher Holyland, a musician/vintner of London, and a Mary Elton. They married on 2 Sept 1749 in Hemel Hempstead (though I've only seen a transcript). Christopher died in London in 1769 in the parish of St Margaret Moses. as far as I know Christopher and Mary had 2 surviving children; Charles born 1752 (no burial found) and Mary, baptised 1760. I've also got a marriage for Mary Holyland, a widow of St Andrew Holborn, to Thomas Wilkinson in Greenwich in 1774.
So I think that Mary Carmichael Smyth was the daughter of Christopher Holyland, and GOK who Thomas Holyland of Bromley was! She would have been v young when married but maybe that's what Gretna was for
Can anyone see major flaws in this argument?
Can anyone find any of the following, which might help ( I don't have a sub for Scotland's People):
1. marriage in Gretna of James Carmichael Smyth and Mary Holyland
2. burial of Mary Carmichael Smyth to confirm date and hopefully her age too
3. burial of Mary's mother Mary Wilkinson, in 1782/3, probably in Buckinghamshire/Westrop?
I know the above is quite wordy but I'd be grateful to anyone who's got this far! Thank you!
