I'm looking for information about Wilhelm Borchardt (my great great grandfather). He may have lived in Pommern/Neustettin sometime between (1833-1910). He married Friederike Borck and they had five children: Max Paul Hugo Borchardt (my great grandfather), Albert Borchardt (a land surveyor), Reinhold Borchardt (a carpenter), Julius (a printer), and Klara (who emigrated to England). Max was a trained artisan in stone and wood carving. He emigrated to Canada in 1906. He was born in 1879 in Pommern/Neustettin.
I know that some of Julius' family ended up in Hamburg after WWII. His son, Max (married to Gretchen Engel), died in 1975 in Hamburg. I have hand-written letters from Max to his first cousin (my grandmother) Ruth Windover (nee Borchardt).
I am curious if this part of my family was forced to migrate to Hamburg or other parts of Germany after WWII, or did some of them remain in the newly formed Poland?
