Oh! wow.....I think the end of it - initials are actually "J. B."
So whatever the last name is ends with the "n." The thing I thought was an "e" is actually the tail of the "J". The J has a spot in in where the ink is smeared. If you hold your screen at an angle you can see the J.
So I'm going with
Harrison, J, B. ?
Thanks for bumping it up again
