I do! My paternal branches are mostly German. Surnames Haese, Hueppauff, Frost, Jantke, Luhrmann, Mattfeld (Mattfield), Creydt, Meyne, Hasenbalg, Albers, and more. A lot are from Hesse, Germany, but also Silesia, and Stettin, Pommern (now Szcezin, Poland).
Researching German ancestors has been frustrating but also very rewarding. The history of Germany is fascinating. I would never have known if I had not have started researching my family tree.
