Raylan, one of an uncountable number of two syllable, surname-like boys' names end in n that are in style these days, is inspired by Raylan Givens, the cowboy hat-wearing U.S. Marshall created by writer Elmore Leonard and starring in the television series "Justified." The Ray part of the name is of course a traditional choice -- it's usually said to mean "wise" -- but the lan takes it out of Old School Raymond territory. Other variations include Raylen, Raylon, Rayden, and so on. The name is also sometimes given to girls, but there are 15 boys named Raylan for every girl Raylan.
Raylan may be on the rise as a baby name thanks to (male) TV lawman Raylan Givens, but the name is also occasionally used for girls: the statistical gender split is 15 to 1. The -lan ending might be thought of as Lynn-like, with Raylan an updated spin on such midcentury concoctions as Rae-Lynn.
