Hello,
Thank you for your reply. Unfortunately I vaen't been able to track Heinrich. The problem is that if he changed his name upon arrival to something like Sawyer (~ same pronounciation as Soya), then he will likely be untracable.
I don't know of several Soya lines that moved to New York State and Virginia, but I am pretty certain that none of my Vogel lin ever moved to the US.
Regards,
Ingolf Vogel
