Hi I do not find any Barlow in the Early Census. However in the 1910 Census there are several Barlow's listed. It is possible that these are children of Hiram Barlow Alex Barlow Brasher, St Lawrence, NY abt 1860 New York White Male Charles A Barlow Pitcairn, St Lawrence, NY abt 1858 New York White Male Gene Barlow Potsdam, St Lawrence, NY abt 1889 New York White Male Julia B Barlow Parishville, St Lawrence, NY abt 1848 New York White Female Sarah M Barlow Canton, St Lawrence, NY abt 1833 New York White Female If we had a township it would certainly be easier to locate your Hiram.
