"Blend of Bryn and Lynn"
The name Brylynn is commonly a female name from the "English" origin.
Brylynn is a modern American formation that pairs the element Bryn with the -lynn ending used in a large group of American girls' names, among them Raelynn and Braelynn. Bryn is a Welsh word for a hill and is also used as a given name in its own right. The combination does not match any name recorded in an older naming tradition.
The pronunciation of Brylynn is BRY-lin.
