I have been researching this family. I am glad to share my notes about him.He married Margaret Smith in 1774.They migrated to Ross Co OH after 1803 (he is still on Broad Creek Hundred tax list) and before 1807(when his daughter married John Van Buskirk in Ross Co).I would welcome any other facts about this family.
1.He is on the 1820 Pickaway Co Ohio census but not on the 1830 census. 2.The 1797 estate settlement of Obediah Smith lists Benjamin as a bondsman. I presume he is listed because his wife is a daughter of Obediah Smith. 3.1782 Sussex Co Delaware tax list shows Benjamin and Obediah Smith on the same page in Broad Creek Hundred. 4.His marriage to Margaret _____ found in Pennsylvania Archives Second Series Vol IX page 458. Marriage was at St Paul's Church in Philadephia. 27 oct 1774 was the date. 5.He is on the 1780 & 1781 tax lists for Broad Creek Hundred, Sussex Co Delaware. 6.He is on the 1800 Sussex Co Delaware census but not on the 1810. He moved to Ross Co Ohio between 1803 and 1807 when his daughter, Juda, married John Van Buskirk. unfortunately there is no 1810 Ohio census available. 7.He served as a private in the Delaware Regiment for seven days between January 1777 to August 1780. This per the DE Archives Vol III pgs 1096/1097 published 1919.
