What about her common name?

When L.Taylor released Heartcup to an English audience, she decided to use a pen name when exploring the unique tonal voice of the fantasy genre.

Prior to Heartcup, she had published the feelgood noir The American Guest under her name Maria Limshage (and who can pronounce Limshage outside Northern countries?).  Her middle names Louise Taylor were perfect for the fantasy genre and reminded her of great authors. Well, there it is: L.Taylor, fantasy writer.
