I do have a copy of the Barnstable marriage record of Jacob Cobb and Annah Crocker. I visited Randolph last summer and found the graves of Abraham and Mary Crocker and some of their descendants, and right next to them was a stone for a daughter of Jacob and Annah Cobb who died young. I think this is another piece of evidence supporting my theory that these families were related. I did not find the graves of any of the other Cobbs in the same cemetery, and I found no probate record for Jacob Cobb in Randolph, so I don't yet know much more about his descendants. I'm going to be traveling in upstate New York this summer, and hope to have a chance to cross over to Vermont to do some more checking. I'm interested in the Abraham and Anna Crocker Cobb families as I believe their sister, Mercy Crocker, is the Mercy Crocker who married Paul Ewer June 6, 1781 in Barnstable. (Paul and Mercy were my 4th great grandparents.) I've found out that Jacob, Abraham, and Paul served in the same regiment in the Revolutionary War during the summer and fall of 1780. (I'm speculating that they became friends and Abraham introduced them to his sisters.)There is a Rev. War pension file for Jacob Cobb, but I've not yet gotten a copy. Are you interested in the Cobb line or the Crockers? Are you a descendant of these lines?
