The Robbinston/Eastport Haydens are descended from Nehemiah Hayden 1648 & Hannah Neale of Braintree (Mehitable, Josiah,000 Benjamin, Nehemiah) The Bradfords of Bayside NB are descended from Nehemiah's brother John Hayden 1635 & his wife Hannah Ames through daughter Lucy. I am also descended from John & Hannah through Luther Hayden of Warren ME.
I see you joined the Robbinston ME group. My family are Thomas & Mehitable (Hayden) Vose, who settled 1790, Martin & Huldah (Bradford) Byrne (settled abt 1808) (Huldah was daugher of Benjamin Bradford, who settled now Bayside NB about 1783), John Harvell who settled Robbinston 1814, Ebenezer Buck (Son of Eliphalet Buck of Eastport) who moved to Robbinston about 1820, and Maude Cleland who arrived about 1826. My mother's family is from St Stephen, St Andews, & Bocabec. I grew up in Harvell & Byrne homes in Robbinston. I live in Wyoming now, but keep in contact with a 1st cousin who is involved in Robbinston Historical Society.
Having said that, no one is an expert on Robbinston. As lumber trade and resulting shipbuilding moved upriver, so did families. You see a migration to Calais and further north, and then to midwest (primarily Minnesota). I think only Stanhope family still lives in Robbinston.
