Re: Jabez Cobb, Canton, MA: 1810
This is a long shot, but I do have a Jabez Cobb in my Nova Scotia database, who may have emigrated back to Massachusetts. He was born ca 1785, probably in Liverpool NS, the son of Sylvanus Cobb and Ruth Godfrey. My source for his existence is the Diary of Simeon Perkins.Jabez' father Sylvanus was the son of Jabez Cobb and Sarah Bartlett, who emigrated from Plymouth MA to Liverpool NS (they were among the founding families of Liverpool). That Jabez Cobb was a member of the Cape Cod branch of the Cobb family, and is mentioned in Philip Cobb's History of the Cobb Family along with his brother, another Sylvanus. I believe that in this family there was quite a lot movement back and forth between Nova Scotia and Massachusetts.
If your Jabez has a child with the name of Sylvanus, then there is very likely a match.
