I don’t think that any hijack about funny names is complete without a pre-emptive reference to Snopes.
Have a friend whose mother and father took a similar tack. The youngest is “Phil.” Sometimes I perform subtle calculations leading me deeper into the mystery of having that many children; it is somewhat alchemic, and some day I’ll invent my own sacred geometry off it.
Their reported motivation for this was to avoid some other family custom of naming kids after relatives, though I’ve always found this answer a bit cryptic as having that many kids, even if naming them alphabetically, will lead to a case where the letter in question can be represented by naming someone after a family member. As they are Catholic I suspect something nefarious, like a secret ritual.
If I find anything I will keep you posted 
I always thought a muff was one of those little tubelike pieces of fur into which ladies inserted heir hands on cold winter days to keep them warm.
As for freaky names, my mother once had a student named Positive Wasserman Jones.
The OED defines muff as:
‘A womans fur into which both hands are thrust, to keep them warm’
I kid you not.

I couldn’t find it online but I remember hearing that he did this to his kids “as my own personal attempt to screw up the social security system.”
Among Muslims in India, Pakistan, and Bangladesh, everybody and his brother — and for once I do mean, literally everybody and his brother — has the first name Muhammad. I am not making this up. We’re looking at (at least) 100 million individuals here all with the same first name.
The result is that nobody is actually called Muhammad; everybody is called by whatever middle name comes after. There are amusing encounters when an Indian Muslim meets, for example, an Arab named Muhammad:
—What’s your name?
—Muhammad.
—Err, no, I mean what else is your name?
—Just Muhammad, that’s all.
—??? (cannot process this information)
I know a Richard Johnson. (He goes by Rick, of course.) He is married to my sister-in-law. When she started dating him, SIL told us that his middle name was Peter–unfortunately (or fortunately), that’s not really the case.

Am I showing my age and naivete here, or isn’t the Wasserman a test for syphilis?
