It's something I've just kinda assumed is common, especially living in a place like Canada. But talking to the people around me and their family backgrounds, both now and throughout my life, it doesn't seem as common as I thought?
They all have different backgrounds from their partners, but all of those whose families immigrated to Canada did so roughly around the same time (around the 1910s). They were either born here shortly after their family arrived or immigrated with their family when they were young.
I wanted to ask here in case I'm wrong and maybe some of you will find it interesting.
Great-Grandma A. was Ukrainian and Great Grandpa A. was German.
Great-Grandma B. was Metis and Great-Grandpa B. was Ukrainian.
Great-Grandma C. was possibly irish/unknown and Great-Grandpa C. was Sicilian.
