I am searching for my ancestor Sven Cantzoff/Canzov/Kantzof who someone recently suggested may have been from Finland, possibly the Vaasa area. His birthdate is December 6, 1764 (or 1766) and he was in Stockholm, Sweden as a tailor in 1800. Before that date, I cannot find any record of him.
I had assumed he was born in Sweden and I just couldn't find any records, but a researcher found another individual with a closely similar last name (in the same time period) who was born in Vaasa.
Is this a familiar surname in Finland? How can I do further (online) research in this area? Any information would be much appreciated -- thank you.
