I don't have any family connections to the name Boelk that I'm aware of, but there are several of my gr-gr-grandmother's siblings that I have been unable to track down. I seen the name Boelk /Bölk often in going through Kr. Greifenberg records. Have you looked in the Hoff Church records for your gr-grandfather's baptism? In They are available through the LDS from about 1807-1874. Please contact me at: email@example.com
and we can continue this discussion. These are the surnames that I am aware of that I connect to in Pommern, all in Kr. Greifenberg and Kr. Cammin.
