My name is Aad Eggen and I live in The Netherlands. If one of your Grand Fathers was born in Holland, he was poseble family of me to. I did a lot of research in the Netherlands about Eggen. Can you be a little more precise about the place of born and data, poseble i can help you. I have some "Matthias" in the Tree born betwene 1700 and 1760. Perhaps it is one of them.
