Our Roots/Nos Racines is an online collection of Canadian local histories in both English and French. Well worth searching if you are looking for ancestors in Canada. I have certainly found a few good leads in a couple of local Ottawa-area histories that I’ve discovered at this site.
A word of caution on local histories: while local histories can be extremely valuable (they can help to establish or confirm the whereabouts of an individual or a family, for example), their information can be a bit loose and vague. Wherever possible, you should verify the information by consulting church records, vital records, census records, and so on.
But on the other hand: the vague and possibly inaccurate information that you find in a local history can offer valuable clues, which can point you in the direction of more reliable sources to pursue.
When I first found a reference to the marriage of Pat Killeen and Bridgit Gallaghan in Garfield Thomas Ogilvie’s Once Upon a Country Lane: A Tribute to The Gaelic Spirit of Old West Huntley, Carleton County, Ontario, Canada (which I discovered at Our Roots/Nos Racines), I didn’t even know that the surname Gallaghan (Galligan) belonged in my family tree. I was searching for Killeen; and Galligan/Gallaghan hadn’t yet crossed my radar screen. And while the approximate marriage date (circa 1846) given in Ogilvie’s local history was off by about 13 years (Patrick Killeen and Bridget Galligan were married on 28 February 1859, as I was later to discover), that reference to a Bridgit Gallaghan opened up a whole new line of inquiry, and led me to the discovery of another branch of my family tree.
Btw, Appendix H (“Irish Proverbs, Folklore, Maxims and Humour”) of Ogilvie’s Once Upon a Country Lane includes a maxim that my dad (a father of four daughters, but no sons) sometimes used to cite: “Your son’s your son ’til he takes a wife; your daughter’s your daughter all of your life.” However, I’m pretty sure my dad used to render it as: “A son is a son ’til he takes him a wife; but a daughter’s your daughter all the days of your life.”
