Lanser Family - Austria
I'm not sure if this helps or not but I have a pretty good knowledge of an Austrian strand of the Lanser family. My father came to England in the 1960s but most of his family were in Austria. Originally they were in a village called InnerVilgratten (If you look it up you'll find Lansers run the saw mill, the petrol station and are in the firebrigade). Around 300-400 years ago one branch (my Dad's part) moved down the mountain to a village called Sillian, there aren't that many Lansers left in Sillian (not many boys so the name got lost) but there are various relations. I have a family tree going back around 200 years but apparently the churches in InnerVilgratten and Sillian have records going back alot further (How far I'm not sure). There is a Lanser house in Sillian (nothing huge) but certainly 2-300 years old. Let me know if this helps.
