My grandfather was Leo MacIsaac (b.1940, Corner Brook, Nfld.)
Leo's father was Cornelious MacIsaac (b.1906, South Branch, Nfld.)
Cornelious' father was Alexander Daniel MacIsaac (b.1872, South Branch, Nfld.)
Alexander's father was Daniel MacIsaac (b.1838, Lochaber, Scotland)
Daniel's father was John MacIsaac (b.1810, Scotland)

The John MacIsaac mentioned above was married to Margaret Kennedy, born 1810. They both died in Codroy, Nfld. If you would like any specifics or other information, I'd be more than happy to oblige.
