Where things lead..

Prompted by the correspondence with Sheena, I became curious as to why the Wilma MacDONALD who married David OAG, had Finlayson as a middle name. Interesting journey.
I nearly stopped looking once I'd hit her grandparents as they were living in the Orkneys rather than Caithness, but then noticed that her father said he was born Pulteneytown, so I persisted one more generation "just in case" there was going to be a connection.
David FINLAYSON, born Pulteneytown in 1827 turns out to be the son of a cooper William FINLAYSON born Bower. At which point my mild curiousity went up a notch or two.
William, wife Catherine (LIDDEL) and family had moved to Whitehall, Orkney by 1841, and were still there in 1851 but then they vanished, and I couldn't find a death for him at all. Nearly gave up, thinking he might have died between 1851 and 1855, so not in civil registration.
Idly searched ancestry for his son Neil and found his death at age 90 as Capt Neil FINLAYSON in Toronto.
Yes, William, Catherine and family had indeed vanished from Orkney (apart from David who stayed behind). They'd emigrated to Trafalgar, Halton Co, Ontario along with a David who looked like he might be William's brother.
That led me to the Bower baptisms of a David and William children of James and Elizabeth (COGHILL) FINLAYSON of Stemster.
Someone must be researching this family as there are patron submissions on the IGI, but I've not yet figured out who they are to see what conclusions they may have reached working back from James and Elizabeth in Bower.
