You might want to check out the New England Historical and Genealogy Society. They have very good records for early Massachusetts and Connecticut settlers.

You also might want to try the local Mormon office. They have excellent records and have some good people who know the records and it’s free.
There is a definite advantage to having Mormons in a branch of the family. I perused my family tree in the on-line Mormon registry, and traced back ancestors for centuries.
Of course, I am a little skeptical of the records going back a millennia or more. While it is amusing to see my family tree going back to the first king of Britain some two millennia BC, I seriously doubt the accuracy of that lineage.
