I found your post today. Ferdinand is my ancestor, but I do not have any information on him. I know more now, due to your post.
I have my direct line to him, but I do not have information about him except he was born in de Liege, Belgium, 1625. Do you have his wife and Children? only child I have is Jean Jacques, bory 1643 St. Paul, de Liege, Belgium.
Were there more children? Do you know his parents and his brothers and sisters?
