Modern combination of Bry and Lynn
A contemporary American invention, Brylynn likely combines the prefix 'Bry' (from names like Brianna or Bryan) with the popular suffix 'Lynn'. While 'Bry' can trace back to Celtic roots meaning high or noble, and 'Lynn' to Welsh roots meaning lake, the name itself is a modern stylistic creation.
