My name is Andy MacKinnon. I also live in Victoria, B.C., and my grandfather, James Moses Coady, was also raised in Margaree.
I believe I'm a descendant of James Coady, one of the 4 immigrant Coady brothers. James (my great-great-grandfather) married Margaret Butler at Chatham, New Brunswick in November 1825. I believe James initially settled in Chatham, in part, because he met Margaret on the ship coming over. James & Margaret had 16 children. At some point (ca. 1830 I think) James and family moved to Margaree.
Their eighth child, William, my great-grandfather, married Jane Dunn. William & Jane had 12 children.
Their ninth child, James Moses Coady, was my grandfather.
I don't know much about these people beyond who they married, and who their children were. I'm working from the same family list you mentioned in your note: my aunt gave it to me, and told me it had been prepared "by a nun". The list I have - which I word-processed and so can supply electronically - is for descendants of James only. Are there similar lists for the other brothers?
