Not that this is an earth shattering revelation, but this one solved two puzzles.
Ann McAdie is a newfound (May 2022) member of the family of Donald McAdie & Catherine MacKain brought to my attention thanks to a "follow" on Donald on FamilySearch.
I was initially sceptical as the profile showed an unverifiable baptism, subsequently proven to be an Ann to a different couple.
I cannot find a baptism for Ann yet, but did indeed prove that she married John Cooper, produced two children, Euphemia and William.
Her death cert. confirmed her parents were indeed Donald and Catherine.
As I explored the family to update my records, I found the 1851 census for the Cooper family (John, Ann and daughter Euphemia) which showed a 2 month old George McAdie grandson with them. Where did he fit?
George's baptism has not - yet - been found, nor his fate after the 1851 census, but it did make me go looking for a likely marriage for Euphemia.
Ancestry Scottish census transcripts don't show marital status, so I hadn't twigged that the Euphemia Cooper daughter of John & Ann was actually recorded as married but enumerated under her birth name.
Sure enough there was an 1850 Edinburgh marriage where Euphemia Ann daughter of John Couper, farmer in Newton in Caithness, had married a William McAddy, joiner Both were described as resident 47 Yardhead, Leith.
So the focus shifted to "Who was William?"
And where was he in 1851?
The only un-eliminated candidate was a joiner lodging in Glasgow in the 1851 census.
Which entry I'd previously tagged as a potential ID for William, HM Customs Officer in London, later married to Sarah Abbot, being investigated for his missing whereabouts in 1851.
The occupation of joiner always seemed a bit of a leap between Caithness farmer's son and a London (but born Wick) HM Customs Officer, so the info had been marked as "of interest" but unconfirmed.
William was shown as single when he married Sarah.
What was the marital status of the 1851 joiner?
I could NOT find the FindMyPast transcript at all, but FreeCen came up trumps and showed him as married, albeit indexed as William McEadie
Great for Euphemia's William, not so great for Sarah's given his marriage cert.
How could I check further?
What happened to Euphemia?
Newspapers reported her death in Louisburgh (Caithness) in Dec 1852, "wife of William McAdie, joiner", several years before he married Sarah.
Given they married in Nov 1850 and the census was Mar 1851, I wonder who was living at 47 Yardhead in 1851?
Bingo, thank you FindMyPast address search
One Robert McAdie, joiner, born Wick, and family, which family later emigrated to Australia.
Robert being known to have a brother William, believed to be the Customs Officer chap in London, where DNA matches between descendants of Robert and of William, Customs Officer, are adding to the ID that William is indeed the son of George McAdie and Elizabeth Rosie in Wick.
I'm convinced that Ann's daughter Euphemia married her 2nd cousin, William, their shared ancestors being George McAdie and Margaret Cooper.
