I am not researching this family, so I cannot vouch for this information, and I am not sure this is the man you are seeking.My granddaughter is a descendant of the Lord family and in their genealogy is the following:
"Lydia Tilden (dtr. of Joseph & Ruth Chamberlain Tilden; b. 15 Nov 1781; d. Aug 2, 1860) married Jairus Bartlett of Norwich, VT.He had his home on a farm on the north side of the Pompanoosue River, a little back from the mneadow, and a shor distance up the stream from what is now Patterson's Flat."
"They had one son, John.After the death of his father and mother he lived unmarried in their old house, some of the time having a family in the house with him, and carrying on the farm in his fashion for about ten years, when suddenly he disappeared, not far from 1870, and never being seen again was supposed by many to have been murdered."
