Named in son Loebel's marriage record. Given that the record names Loebel's mother as a Nothmann, I assume Jacob and Pine were cousins, Jacob being a son of the first Cohn in the family, Joel Loebel.

Jettel's father is identified as Jacob in a note in the record of her daughter Marjana's birth; this Jacob is the only one I know of in the right time and place, so I have made a tentative connection.
