Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon.
Saint Stephen was a deacon who was stoned to death, as told in Acts in the New Testament. He is regarded as the first Christian martyr. Due to him, the name became common in the Christian world. It was popularized in England by the Normans. This was the name of kings of England, Serbia, and Poland, as well as ten popes.
