Thanks for all the comments thus far
J.A. (John Arthur) Bebb was the 2nd mate onboard and witnessed the signing of most of the crew. I find it interesting that he witnessed most of the crew, yet John's witness signature and potential ship was scribbled down really quickly...
Yes it could say James Thorpe as the man witnessing John signing on or it could be something totally different. That's what makes this crew list so hard, as I have seen so many others which are very easy to read.
