Of course as soon as I post this, I find my answer in the next couple of posts I look at!
If I have it right, Samuel Pinkham (d.1780) is a cousin to Joseph Pinkham (d 1819) of Pinkham Notch fame. Their fathers were brothers ( Richard Jr and Thomas).
Now we'd like to know if we have relatives in NH we can visit when we go to see Pinkham notch?
As a tidbit--I used to be a park ranger in Yosemite. Visitors from New England who saw my name badge with "Pinkham" on it were forever asking me about Pinkham Notch. Now I know my husband is indeed related! Yeah!
