None of your letters mention about what years you're in, or even a vague mention of what state.
I have a Samuel McKee who came to Westmorland Co., Pa. in ? and died there in 1780. He had a son, Saml., followed by my James McKee, who went to Ill. and died 1864.
He was followed by Saml. Wallace McK, his son Frank Wallace McK and then Donald Wallace McKee. I have always wondered where the Wallace came from.
