My grandfather was JOHN HARTMAN(N) born in Germany in 1880. His father was THEODOR HARTMANN born 1857 who married Mathilde TESSMER (TASMAR)(TESSMAYER) born 1861. The family came to USA in 1893
from the Konitz/Schlochau area. John Married ANNA MICHALKE, daughter of Lizzie and Ludwig REHWINKEL(RAYWINKEL) in Wallingford, Connecticut in 1900. I am attempting to locate any relatives who might still be in that area of West Prussia. I would appreciate your suggestions.
Hopefully,
John Hartman
