Hi Robert, There was one other child Abraham, and we feel he must have d/y but I have info on the other three children as I descend from Sarah Jillis Fonda b 18 Jan 1645 Friesland Netherlands. I will be happy to work with you on the American Fonda's with what I do know. I can tie this family into Henry and Jane Fonda the actors to the Roosevelts! Through Sara's brother Jillis Douwess Fonda. Let me know, what you want. Regards Bonnie Ferguson I am slow, I don't know how to send a file but if you are interested in my info I will be happy to help you all I can.
