"Blend of Chris and Lyn"
The name Chrislyn is commonly a female name from the "English" origin.
Chrislyn is a modern American formation that joins Chris, a short form of Christine or Christopher, to the -lyn ending that became productive in English-language girls' names in the twentieth century, as in Carolyn and Marilyn. The name appears in United States birth records from 1951, which fits that pattern of coinage rather than an older inherited name.
The pronunciation of Chrislyn is KRIS-lin.
