Hi Kay, thanks for your message. I will take your advice - never thought about trying Hunt. Actually, I also have a William Buchan and Kate McIntyre in my tree. They were the parents of Margaret Buchan born about 1844 who married John McIntyre on 7 March 1866 at the Taynuilt Hotel, Muckairn, both of Oban. John McIntyre was a slater and son of Mary McFadyen and Peter McIntyre. Note the spelling of Buchan - Margaret died in 1890 at Lorn Combination Poorhouse. This Margaret Buchan is, as far as I know, not related to my Glasgow Buchanan's although you never know.
Perhaps its time I took the Glasgow Buchanan's out of the too hard basket. Kind regards, Sarah.
