Where does the name Duddy come from?

a German rapest

actually. this is completely wrong and stupid and misspelled.

The correct answer is that the name 'Duddy' comes from the Hebrew name 'David', meaning 'The Beloved.'

This is directly related to the story of David in the Hebrew religion, which expands further than the Christian religion. The story of David begins with him as a shepherd who fights Goliath, who is assumed to be 9 feet tall and a savage, killing him and saving the town. Saul, the king, gives David the honour of becoming commander of the army, however, Saul later on goes after David trying to kill him. David kills Saul, and becomes a great king and leader, uniting his people.
