[Magdalen] Coon/Cooning.

[M J _Mike_ Logsdon]

Sometimes it's a surname (unfortunately):

Now, how a white family ended up with such a surname away on back in the aeons of time, is anyone's guess.  (Raccoons? Melons? The Bad Way?)

As for "jewing" someone down, I learned that from my family, but didn't really get the point till I went to college.  I owe much (not all) of my current outlook on life and creation from my non-white ex-wife.
