Ninian Riley, the son of Eliphaz Riley, was born March 18, 1725 in Montgomery Co.,MD. and died 1814, in Fayette Co. KY. He was a farmer and a Baptist Minister.
His reason for leaving appears to be harrassment for supporting the Patriots and the fact he converted to the Baptist faith. He had been a Warden in the Rock Creek Episcopal Church. At least two of his sons were later ordained ministers in the Baptist faith.
