Interesting, the surname I'm connected to is Dauven and just very recently discovered it. Specifically Michael Dauven and family. Johann Dauven emmigrated from Ferschweiler in 1852 to Washington county WI and had neighbors named Hames-Hammes. If you would like to share more my email is firstname.lastname@example.org
I'm wondering if the Hammes in WI are connected to Minnesota and I believe that there are Dauvens in MN as well. Like I said I just discovered the alternate surname spelling I was researching.
