You are Welcome.
I probably don't have much if anything that you already have. John is living with his step-son Charlie
in the 1900 census and in 1910 living by himself. I could not find the 1860census that shows John Living with the Harris Family. I have his death cert... assuming you already have all this info.....Also believe he aged himself to be closer to Amelia's age, especially if his parents married in 1843....
