The Ira Williamson I find was b. abt 1814. In the 1830 Census for Hunterdon Co., NJ is one--but would be too old for the one you want. Maybe his father--or Uncle ?? In 1840 there is one who probably is him. He shows 20/30 wife 20/30, 1 male & 1 female both under 5. I'm enclosing transcript of 1850 & 1860 Census. Also transcript of US Tax Assessments Lists for Sept. 1862--Dec 1863. There also is one for Jan-Dec 1865, & 66. They show hims as being taxed on Auction Sales. Hope this helps. No Relation.
