Dale,
Thank you so much for pointing me to the Hingham genealogy site. It's all there! Now, the stumbling block lies in finding when and where Mehitable was married. It appears she was might had been married in Milton. Her elder sister was also possibly married in Milton, so I wonder if her guardian was living there. Intriguing.

I have struggled with getting copies of early records from the Mass. state archives. Do you know of an easier way?

I see you are a member of the Mayflower Society, I am working on my line through Francis Cooke (unrelated to the Herseys)
