Yes, this is the same William, but I have his DOB as 15 Dec.1802. I believe this is the right date, because my husband is descended from, Ephriam, and William was Ephriam's older brother. William married Mary Ann Kelly, b.1811 OH., on 4 Oct.1829 at Jackson Co., Ind. I have that William died 5 March 1851 in Warren Co.,Ill. How are you descended from William?
