Margaret is the only known prograde irregular satellite of the moons of Uranus. It was discovered by Scott S. Sheppard, et al. in 2003 and given the provisional designation S/2003 U 3.[8]
Confirmed as Uranus XXIII, it was named after the servant of Hero in William Shakespeare's play Much Ado About Nothing.[1] The name was also chosen to match the name of Sheppard's mother.[9]

So, I just simply did a search for "Margaret," which was my Mom's name, on the Web, and "Shakespeare." And it came up with Much Ado about Nothing. And I said that's it, that's what I'll name it.
