I am a third-great grandson of Martin M. and Amy (Marshall) VanDerwerker/VanDerwerken/Vanderwarker. I have their original Bible pages, as handed down to me. Specifically, they do list the marriage of Orlando V. to Sarah J. Baldwin as being April 12, 1884. I'd be interested in hearing from anyone interested in the V. family history and genealogy.
