As far a I know Joseph could quite possibly be John B Allen's grandfather.I have info on the children of William b. 1782 and Jacob b. 1790 and Abraham b 1787.Joseph was not their son but I don't have any information on the children of Isaac b. 1788. I have information that Isaac married Sarah Hawkins on 31 Aug 1813 but I have not been able to confirm this.The Indiana connection fits because Joseph Allen b. 1811, the son of William migrated to Johnson Co IN where he died in 1882.
