Ask her about tourtière, and if her family served it at Christmas. It's an easy enough dish to make, and she might like the tradition. Some people don't, but our family does like it.
My family's roots go back into the 1600s, in Lachine, which is a suburb of Montreal. In fact, in 1689, a couple of my ancestors were killed when the Mohawk Indians attacked Lachine in 1689. My roots go back to a French soldier who was an Acadian. When he mustered out, he went to the Montreal area, where he married, and raised a family. I was even able to track him back, to France, and his parents, and beyond, believe it or not. In fact, I found lineage all the way into the mid 1500s.
Ancestry is interesting. On my wife's side, very interesting. A second cousin of Princess Diana on the Spencer side, and roots dating back to England and the early settlers of Virginia on the other. In fact, she has direct lineage to two soldiers, one an officer, who fought beside George Washington in the American Revolution, and a whole lot of relatives who fought on both sides, during the American Civil War.
On my second side, migration from Germany, back in the latter part of the 1880s, and settling in Northern Wisconsin, where my Grandfather was nicknamed "The Johnny Appleseed of The Midwest," by a writer for Ford Times, when an article was published about him and his work in stocking lakes with fish, long before anyone else was doing it. When he was still in Germany, he was a soldier, and a body guard for Kaiser Wilhelm, but was sent to the US by the Kaiser, because his life was threatened when he knocked one of the Kaiser's political enemies on his rear when he tried to touch the Kaiser. The man essentially put a contract out on his life, and the Kaiser liked him, so he gave him some money, and sent him away for his own protection.
Genealogy is fun, but it takes up a lot of time. It can also be very expensive. I'd suggest also doing DNA to go with it, because when you combine the two, you can get the facts correct, because DNA don't lie.
