What Brynn means
Brynn means a hill. The Welsh bryn is a plain topographic word, and it appears across Welsh place names from Brynmawr to Bryn Celli Ddu.
Where Brynn comes from
Brynn comes from the Welsh bryn, a hill, one of the commonest elements in Welsh toponymy. In Wales Bryn is a masculine given name and remains so; the doubled N and the shift to girls are both American, following the pattern that also moved Lynn, Robin and Ashley. The name's American life begins in earnest in the 1940s. It should not be confused with the Scandinavian Brynn or with Brynhild, which come from an Old Norse element meaning armor, and are a separate line entirely.
