Rye island or rye hill
Rylin is a modern American invention, likely derived from the English surname Ryland or a blend of Riley and Lynn. It traditionally refers to a meadow or island where rye was grown. As a contemporary coinage, it fits the trend of using 'y' and 'n' endings for a sleek, unisex sound.
