Mosley, former best known as the surname of author Walter, has been put in play as a first name for girls by football great Peyton Manning, who used the name for his twin daughter, sister of Marshall. Alternate spellings are Moseley and Mosely and the first syllable rhymes with Rose.

This rare name received national attention in 2021 when actor Frankie Muniz and his wife Paige named their son Mauz Mosley. The variation they used stems from the Hebrew word Mauzzim, literally translating to "fortresses" (mauz would be the singular, "fortress"). Some versions of the Bible interpret Mauzzim in context as "God's protectors."

Mosley has seen a handful of uses — mostly among baby girls — since 2012, the year after Peyton Manning gave it to his daughter. It's much more familiar as a surname, such as that of novelist Walter Mosley.
