My father's name is traced from Walllonian immigration around 1650, how it moved from there is unknown, althuogh it's suspected the originally be German.

My grandmother's (on my father's side) name is most researched that I've seen and is also traceable to around the same time (IIRC is was around 1620). Was Swedish at that time and before that it starts to get hard to trace due to lack of writtten records.

My grandmother's (on my mother's side) name is basically unknown. Actually not even remembering it atm .

But my mother's name does seem to have quite a bit of history, although I haven't been in contact with the genealogist in the family, only heard in second hand. It seems to be originating from Germany in the 13:th centuary and the most famous members were residenting in Danzig during the 16:th centuary. You can find that line actually mentioned in history books.
Admittably lacking quite a bit in the actual bloodlines, but having your rare surname mentioned in history books are well quite something .
