Juliane,
I am also a descendant on Abraham Beil through his son John, who was my gg grandfather. I was not aware that Abraham had a son Isaac. Did you know about John? I would love to have Isaac's birth, death and marriage info as well as his children for my record if you would be willing. I can also share my info on John if you want it. Thanks
Do you have Balthasar's parents? I can share that with you as well.
