I have heard of a number of Ebenezer Kingmans. The Ebenezer in my direct line had thirteen children to my knowledge. He was married to Catharine Silvernail. He had children born between 1791 and 1815. I don't know of any child of his born in 1805, but he did have sons born in 1804 and 1806 (Peter and Milo, respectively - Peter is in my direct line). Up until about 1808, all of Ebenezer's children were born in Ancram, Columbia County, NY. The remaining children were born in Kinderhook, Columbia County, NY. Ebenezer originally came from Stonington, CT and moved to Columbia County, NY, around 1787 or 1788. The Kingman family originated from MA.
