I also knew they were from a village called Bannia. Eventually, I started to pursue genealogy and needed a better sense of where they came from. That was in the early days of the Internet. Ancestry didn't exist back then. but I was searching out people named Bertolo from around the world. The one I found in Sudbury, Ontario was a cousin. The lovely fellow in the Friuli I couldn't connect to our tree.
It's a bit odd to blog about the province my family isn't from (or isn't from anymore), but that's the sort of thing that happens when you're following and A to Z challenge and have to blog on U. Come back later in the week and see what we can make of X, Y and Z. I'll give you a hint, Z is delicious.
