The surname St. Louis was first found in Brittany, where the family held a family seat since ancient times.
It is generally thought that Louis IX (1214-1270), commonly known as Saint Louis, was the originator of the name. He is the only King of France to be canonized in the Catholic Church. He was crowned in Reims at the age of 12, following the death of his father Louis VIII (1187-1226), nicknamed the Lion, King of France from 1223 to 1226.
