A Joseph Skidmore with a wife named Rebecca, a daughter Susannah, and a son Joseph died in Delaware about 1708. His will was written April 6, 1708 and can be seen on Ancestry. Register of wills, book A-D, 1680-1710; F-G, 1725-1730; Miscellaneous wills, 1732-1798 [Wills, 1680-1860; and index to wills, 1680-1948; Author: Kent County (Delaware). Register of Wills; Probate Place: Kent, Delaware]. I found a number of unsourced claims about him, but his will (viewable on Ancestry) seems to be the only actual document. I didn't find him listed in the American Ancestors database, suggesting he wasn't born or married in New England.
