Answer
Morse's middle name is Finley, which has historical roots. Samuel Finley Breese Morse, the inventor of the Morse code, was named after his father, Reverend Jedidiah Morse, a prominent geographer and historian. The name Finley was derived from Reverend Morse's maternal great-grandfather, Rev. Samuel Finley, a Presbyterian minister and president of the College of New Jersey (now Princeton University).
