Thank you, Lilybell.
I've been searching for Wm. for many years, and at first thought I had found him as the son of William and Eliz. as you did. His obit DOES say he was born Paisley.
Unfortunately, I now have his two marriage certs from Nova Scotia (1869 and 1881) and they both say his parents were William and Margaret. I've searched censuses, BMDs, etc. with no further luck, and since he joined army at 17 or 18, those records are where I have been placing my hope.
