Follower of Christ
Kerston is a modern variant of Kirsten or Kiersten, which are Scandinavian forms of Christina. It ultimately derives from the Latin name Christianus, meaning 'a Christian' or 'follower of Christ'. While rare, it follows the trend of using 'K' spellings and 'ston' suffixes in American naming patterns.
