How nice to hear from you! I will attest to the fact that your grandfather did some excellent work on your family line! In other words, other than updating it to include any new additions to the family and possibly expanding it to include any new new cousins discovered in the earlier generations, I can't imagine what might need to be fixed up! In the early 90s, Lou, Louise Pfankuche and I corresponded with each other...so our work on the early VDCs is pretty much in sync. I believe that Lou was the major (possibly the only) genealogist working on the branches of the VanDerCook family that remained in NJ. It's good to know that his family has saved his work and appreciates what a marvelous body of research he left.
