Brynley is a modern American name that joins Brynn, from the Welsh word bryn for "hill", with the popular ending -ley that means "meadow" or "clearing" in Old English. The spelling Brynlee is more common in the United States; Brynley reads as the slightly more traditional version of the same idea. Brynley has held steady just outside the top 1000 for a decade, between number 1132 in 2017 and number 1506 in 2021, and ranks 1183 in 2025.
