I know that John was born in Maine in about January 1814. He died on 13 October 1853 in Jackson, Waldo, Maine, after having six children with Sophia Sylvester. Relatives have said his mother was named Dorothea Jenness (not supported by sources, maybe?). He married Sophia on 24 April 1842 in Penobscot County, Maine. Relatives have also said he was the son of Joseph Jenness (1786-1869) and Theodate Drake Jenness (1786-1836). This is NOT correct as the couple only had three children: Mary Jane Jenness Morse (1810-1833), Samuel Drake Jenness (1813-1843), and Abraham Drake Jenness (1818-1863). He was possibly also born in Jackson, Waldo, Maine. Does anyone have any ideas?
