Have seen a lot of information regarding Adam (and I have copies of relevant information from the Wickersham book), but I am descended from Jan (Adam's brother). I have the bit of information that's in the Wickersham book, and have read the information from Pearson about the 1690 massacre in which Jan was one of those kidnapped and taken to Canada.
Beyond those sources, I've found very little mention of Jan and his descendents (my line goes to Simon, to Johannes Symonse, to Johannes, to Jacob, to John, to Smith Joseph, to A.E. (The last mention in the book on our line is my mother.)
Was wondering if you've come across any information about the lives of Jan and his descendents? Thanks.
