Is your Ambrose Morton any relation to Thomas Jacob Morton, Ira Stockton Morton,Andrew J. Morton, Miranda G. Morton, or Rachel Ann Morton? The people that I just listed are children of Jacob Ira Morton and Rachel Fuzett.
Jacob had a brother named Gilkey Morton; he and his family lived in Lewis County for a while.
I am connected because Gilkey and Jacob Ira also had a sister named Clarissa. She is my 3rd great grandmother - having married William John Irven. The Irven family lived in Canton for many years.
