Well, that serendipity from yesterday was a wonderful sidetrack.
Along the way I've found another son of David FAIRBAIRN and Charity WALKER married in Michigan (William E) and got sidetracked onto trying, unsuccessfully, to figure out who an Isabella Elliot FAIRBAIRN was, born Ontario 1850, married the Rev James Anderson Ross DICKSON (somewhere, possibly London Ontario), and lived Galt Ontario.
And it reinforced how useful it can be to squirrel away information that just might come in useful later.
William E, the son of David and Charity married a Rosa KUHNLE, who sounded a bit familiar. Sure enough, I'd found and saved, and obit for Rosa FAIRBAIRN nee KUHNLE last year.
While trying to solve who Isabella Elliot FAIRBAIRN was I also stumbled upon the baptism of an Isabella MITCHELL, dtr of an Agnes FAIRBAIRN and Alexander MITCHELL baptised in Chatham, Ottawa River Canada East by the same Minister who married David FAIRBAIRN and his first wife Prudential ARNOLD.
Haven't figured out who this Agnes is either, anyone know?
