Thomas John Tilton appears to be a made-up person.
According to Tilton researcher William Haslet Jones, there are records in Narborough, Warwickshire, of a Thomas Tilton who witnessed the 1515 will of a Henry King. (LRO, 1515, #42) There was also a John Tilton who witnessed the 1517 will of a Nicholas Yongle (LRO, 1517, #124).
There is simply no evidence of any individual Thomas John Tilton, which would have been a highly unlikely name in 1359, the purported birthdate.
He seems to have been created to provide a father for William Tilton-82, whose will is dated 1542.
