I don't have an answer to your question, but I'm curious as to your connection to Henry and Nellie. I'm the grandson of one of their youngest daughters, Dorothy DeRoo. We unfortunately lost my grandmother this weekend, and I would love to honor her by finding out as much about her history as I can. Please e-mail me at firstname.lastname@example.org
if you have any information about either Henry or Nellie and their family history.
