Brock is a rock solid name, with a touch of preppy sophistication. It ranked solidly in the 200s-300s from 1975 until 2014, when it slipped out of the Top 400. It now ranks at Number 450.
Among Brocks who lived up to their name are Brock Peters (actually born George), who played Tom Robinson in To Kill a Mockingbird; Brock Pemberton, a founder of the Tony Awards; and Brock Chisholm, the first director-general of the World Health Organization.
Brock is the traditional name given to a badger in folk tales.
