There was the daughter of billionare Texas oilman Big Jim Hogg. Her name: Ima Hogg
And Frank Zappa's kids, Dweezil and Moon Unit.

My favorite was a fellow Army officer who's family was from Thailand. His last name Arnukunpitaya. And it usually was the first name some poor Sergeant had to attempt to call at 0500 formation. After the third, fourth, or in a few cases with a very determined Sergeant,a fifth attempt, he would invariably be titled "Lt. Alphabet". He eventually changed his name to Jones. Tough little guy though. And former Special Forces enlisted.
