 Willoughby Patterne is the protagonist of the George Meredith novel, The Egotist. Willoughby Sharp was a contemporary artist, curator, critic and founder of the seminal art magazine, Avalanche.

Louetta, an elaborate diminutive of Lou or Louise, was used consistently from the 1910s-1960s' but has never been given to more than 50 baby girls in a single year.
