Something for the history buffs among you…
When I was in Winnipeg over the holidays, my grandmother pulled out her family history photo album and let me have a look through it, and — to my surprise and delight — tucked inside were both of my maternal great-grandparents' passports. So I did what all people of my generation would do: I took out my phone and started taking pictures. Considering I didn't use flash, and considering the pictures were taken with my phone (which is definitely not a top-of-the-line model), the results are surprisingly legible — if you can read Russian, that is.
Russia was and is a very diverse country, so it shouldn't surprise you that much that my mother didn't learn until relatively recently that her grandparents spoke Russian. Growing up, I was always told that my mother's mother's family was German (German-from-Russia, as my mother called it), and I never really gave much thought to the “from-Russia” part of it. It turns out, though, that there was a sizable German population settled around the Volga/Saratov. They had a confusing/tumultuous relationship with the soviets, at one point granted a fair amount of autonomy as the Volga German Republic, and at another banished from the land (and, I believe, sent to Siberia — but who wasn't at some point?). My direct ancestors left before then, but I'm sure that there are relatives of mine who didn't fare so well. And despite their “otherness” from Russia at large, they did hold Russian passports:
And there you have it.
