A forename for 'Miss Moneypenny'? (4)

I believe the answer is:

lois

I'm a little stuck... Click here to teach me more about this clue!

'a forename' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I can't see?

I can't explain the rest of the clue.

Can you help me to learn more?

(Other definitions for lois that I've seen before include "-- Lane, 'Superman' character" , "Superman's girlfriend" , "- Lane, Daily Planet reporter" , "- Lane (Superman's girl)" , "- Lane, girlfriend of Superman" .)

I've seen this clue in the Evening Standard.
