I am not 100% certain Joseph moved to Ohio. I do know that he owned land in Ashtabula County that he sold to my 4th Great-Grandfather, Timothy Alderman. I have a copy of the deed. Word of mouth has spread (and is somewhat mentioned in Aldermans in America) that Joseph was buried in Windsor Mills, Ashtabula Co., OH. It would make some sense as his three grandsons moved to Ohio and then his son Elijah (or similiar spelling) moved to Ashtabula County later. The vast majority of Aldermans in Trumbull Co. and Ashtabula Co., OH and Mercer Co., PA descend from Timothy, Jonathan, James, and Elijah Alderman. Piecing them together is the difficult part. I am descended from Timothy Alderman. My research focuses on the descendants of Timothy, Jonathan, and James Alderman. I have not learned all that much about Jonathan Alderman's descendants. There are not many records about him that I can find in or around Trumbull County.
