Hello!
I have no access to Canadian records

and could really use some help tracing some Taylors in Montreal.
This is what I know:
Archibald D Taylor m Mary Davies in Scotland. (Have no dates for this couple at all!)
They had a son born in England on 24th May 1830: James Williamson Taylor.
Then about the only other documentary evidence I have is photos of various Taylors, all taken in Montreal -- for once, helpfully annotated on back. (I assume before being sent back to my relatives in UK). These are:
James Williamson Taylor (undated; but photo depicts late-middle- aged man)
Thomas M Taylor (dated 1882; late-middle-aged man)
Mrs Thomas M Taylor (dated 1882; late-middle-aged woman)
Mary Isobel Taylor (dated 1891; girl in mid teens-ish)
I know James and Thomas also had a sister: Margaret Peploe Taylor. This is known because she married her cousin, Huntley Mackay (b Inverness, Scotland; emigrated to Canada in 1840, aged 18 -- we know quite a lot about HIM!) in 1868 in Montreal.
Since there is evidence of all three siblings being in Montreal, I assume their parents likely emigrated there. But I have no idea when (or even, for sure, that they did!).
Although the Taylors are fairly distant relatives of mine, it would be really lovely to be able to add some flesh to these names and photos. Anything that anyone with access to Canadian records can turn up without going to a great deal of trouble (census records, perhaps?) would be very much appreciated.
Many thanks!
