I'm research ing origin/meaning of my last name. It's currently spelled Lastufka, but was actually spelled Lastuvka when my ancestor's were in Bohemia in the 1800s (they emigrated to the U.S. around 1900; they were from the Hlinsko region). We were told that our name means "swallows"; however, swallows in Czech is vlaštovky. Any suggestion as to the exact origin/meaning of my name? Thanks
