If Samuel Dunn can't be found, maybe Mary Blackman? I have her cemetery records. It states she was born in New Jersey, January 11, 1822. She died in Wichita, Kansas, April 6, 1916, and is buried in Maple Grove Cemetery. She was married to Samuel L. Dunn who was born in Ohio. Is there a record of a Reverend John Collins born about 1769-1770? He was a Methodist minister. He married Sarah Blackman. I haven't found if she was related to Mary Blackman or not. Thanks.
