Lucky guess!
From about 1670 to 1800 a branch of my family lived along the CT river. Hadley to Northfield. Years ago I was in Whately looking for my 5x great grandfather's grave. I was looking in the big cemetery across from the old school that had a sheriff's substation in it. Right next to the school a country-style outdoor wedding was getting underway. A friendly lady asked me what I was doing in the cemetery. I told her family research. She asked what families. Off the top of my head I said Dickenson, Nash and Allis. She looked like she'd seen a ghost and said "the bride's a Nash, the groom's a Dickenson, and I'm a William Allis descendant!" She said welcome, cousin and invited me to the wedding, but I was wearing cargo shorts and a football jersey, so I declined. I gotta get back to Whately and get a burger at the diner.
