After Robert Ripley died and his lease expired, the 1000 acres were leased to Michael Keiver. Michael Keiver died a year before his lease expired in 1818. When Thomas Cochran's estate was settled in 1826, a deed to his son William George Cochran described the location of a Mr. Keiver's house, on an island in the marsh. William Cochran's deed also says that the western boundary of the marsh was a line drawn from a birch tree on that island to Henry Ripley's house. Wow! We know that Henry's house was located at the corner of today's Higgs Road and Nappan Roads on the south side of the Nappan River.
Of course, we don't know who "Mr. Keiver" is in the deed since Michael Keiver had died in 1817. But it took from 1802 to 1826 to settle the estate so who knows when the survey was actually done. Do you think it's too much of a stretch to believe, since Robert Ripley and Michael Keiver both leased the same property and lived on islands in the marsh, it was the same house? And that Henry Ripley lived right across the Nappan River from his father?
