John & Mary Hammer Adamson did have a daughter named Eleanor. Some databases seem to have confused this Eleanor with the daughter of John N.'s brother Simon Jr, as Simon also named a daughter Eleanor. Simon's Eleanor was some younger, probably born about 1813.
Given John & Eleanor's ages, they could have had older children. There were several John Tharp's in Indiana in 1840, none definitive, but several are the wrong age or have no children.
