A man forced his pig and he died!
When I read it this, it sounded to me very like 'you can take a horse to water but you can't make it drink' In other workds, you can't force anyone to do anything they don't want to.
Names - I think the tudor names are a bit of a red herring. There were loads of older names floating around before that. Think of Rosamund, Eleanor, Ethelred, Edmund etc. they fell out of favour but they were there before Thomas and Richard. (and name ending in nd is old I think??)
Then the Bible names - far more than you think - Lucy is female version of Luke, Abigail Naomi, Timothy, Benjamin, etc etc , as well as the 12 disciples, all of Jacobs sons (Reuben, Joseph, Simeon, Levi,) Old testament famous people - Daniel, Noah,
Then you have the Victorian habit of using the prophets - Jeremiah, Isaiah, Ezra, Amos etc.
Then add in things like names of flowers and months (also very Victorian) Lily, Rose, May April.
And then one name gets so many variations, probably due to accent, Elizabeth, Eliza, Liz, Lizzy, Betty, Bethan, Lizbet, Liza, Lisa, Beth.
