"Blend of Darla and Lynn"
The name Darlynn is commonly a female name from the "English" origin.
Darlynn is a modern American formation built from Darl-, the element found in Darla and Darlene, combined with the -lynn ending seen in names such as Marilyn and Carolyn. It first appears in United States birth records in 1937, within the period when -lynn forms were being coined in American naming. The name is best described by its parts rather than by a meaning inherited from an older language.
The pronunciation of Darlynn is DAR-lin.
