I’m trying to build a family tree of my extended family, and the results are here in as PDFs, in verious versions. The newest and current version is the first in the list.
Our surname is a bought and registered family name, meaning no other people in Denmark can use the name, so all Seindals here in Denmark should somehow be related to me. The name first appeared when my paternal grandfather and five of his six siblings decided to change their surname from the very common Jensen to a name of their own invention, Seindal.
