Alfalfa, the tall skinny kid in the Little Rascals, Our Gang Comedies, Real on screen name his parents used was Aloysius. (Oops, I misspelled it before. . . Although Aloycius is an accepted alternative uncommon spelling. )
The protagonist millionaire FBI agent in the series of books written by Douglas Preston and Lincoln Child, is named Aloysius Xengu Leng Pendergast. Great series of mystery/suspense
Loved the little rascals.
