Hello, while going back through this Vredenburgh line, I came across your reply. Did I ever respond? I believe that you are my cousin, Lee Vredenburgh was my grandmother's brother. Our cousin, Maxine Schafer (Amy, her grandmother, was sibling to ours) recently died. I feel that she might be "helping" me now because that was our aim, find the Vredenburgh line.
Please email me, if you are still interested in this line.
