"Blend of Mae and Lynn"
The name Maelyn is commonly a female name from the "English" origin.
Maelyn is a modern American blend of the given names Mae and Lynn, built on the same pattern as other -lyn combinations such as Raelynn and Brynlee. The name first appears in United States birth records in 1982, which fits a twentieth-century coinage rather than an older established name. Neither element carries a combined meaning beyond the two source names.
The pronunciation of Maelyn is MAY-lin.
