There is a John B Wilkes a composer and music arranger (not sure where he lived) about this time period.

Notice the "not to be confused with John Wilkes" ( a different John Wilkes)

I believe this is a tune he arranged. I am not familiar with it, but it is a nice song.

The point being, the name is not that unusual or unique.
