We don't know the birth place, date or parents of the husband of Joana Arnold.
Nicholas Hopkins and Mary Poole were invented in a book. The real Mary Poole died childless before 1536. See them at their section here:

None of the siblings listed for him are related to each other by any document and there's something wrong with each of them. If know know anything about Stephen Hopkins of the Mayflower you'll notice the errors on "John" (Hopkins-3048).
Joana Arnold isn't the "Dudley" woman. That was a big mess.
"Some sources state David Dudley of Dorking, co. Surrey was a son of Robert and that William Dudley, immigrant to Connecticut was David's son. This has since been proven to be false. “The English Origins of William Dudley of Guilford, CT” by Martin E. Hollick The American Genealogist 82 (2007):63-75. David of Dorking had a son William but he stayed in Surrey."
Joana Arnold's & Wm Hopkins' dau Frances didn't marry John Mann and didn't have a dau Mary who married John Hampton. She married William Mann and had a dau Mary who married John Lapham.
