Hi Bob,
I just realized why your name sounded familiar. We have communicated before regarding my gggrandfather Beriah Andre Watson who was also married to a Traphagen. I found some promising information for you on ixquick metasearch. The search I used was Alonzo Whitney Adams The URL is ixquick.com.

Go here:

If you have trouble finding it let me know and I will post all of the information found there. I think this is his father. The dates and names are right.
Happy Hunting,
Linda
