Uriah Heep probably put most people off the name since the publication of
David Copperfield in 1850. Dickens used it for a thoroughly nasty character with an equally dreadful mother, both of whom but especially
Uriah are skilled confidence tricksters who claim to be humble and God-fearing.
Uriah ends up in prison where
David meets him and finds him, unsurprisingly, keeping up his image by reading, I think, a hymn book; perhaps a prayer book, I haven't read
David Copperfield for years! And I think that in the early 1900s people were much more likely to read Dickens than they are now, and so I'm not surprised it's more popular now than then.
