No founder, proclamation or registration record has been located for National Brayden Day. One holiday-listing site that has archived its February 12 page every year since 2013 carried no Brayden entry as late as March 2023, and the earliest third-party listing found anywhere is an archived capture from March 2024, which dates the listing rather than the day.
A surname built on a fish
Brayden is not an old name. The thing underneath it is. Behind the Name files Brayden as a modern English variant of Braden, which came from the Irish surname Ó Bradáin.
That surname means descendant of Bradán. Bradán is a medieval Irish byname, and the reference gives it two readings rather than one: it means salmon in Irish, or it may be built from brad, meaning thief, plus a diminutive ending. The root is disputed at the source, not by us.
