[Ger-Poland-Volhynia] Descendants of August Klappstein b. 2 May 1856

[lotus89]

Hello,
I am searching relatives in Canada or the USA. (I live in the USA) The last
name is Sonnenberg. I don't have first names, but they are the descendants
of my grandfather's brother.
My grandfather was Leonard Klappstein, son of August Klappstein b. 2 May
1856, and Karoline Kotke b. 18 March 1873.  The area in Poland was
Marawil/Marowil.

Thanks, and happy new year!

Angela
