(see the <project> on the Weidner famliy) If his wife arrived with Lutwig/Ludwig Schott/Shutt on the same ship, then we might expect that Jacob and Elizabeth married afterwards.. (not much is certain here)
The following would be a good fit:

1. Johannes arrived on Sep. 1730 at Phila. in the Ship Alexander & Anne,
2. Hans Michel (who we may hear of as simply Michael (these two arrived together)

~• either of the above may be Jacob's father (see <project>) ; see also: document )
