Samuell, of Hebrew origin, means 'name of God'. It is an alternate spelling of Samuel, which has been widely used since medieval times. This name was popular among the Puritans and has experienced a resurgence in recent years. Samuell appears briefly in the New Testament as one of Jesus' disciples.
"The name Samuell experienced a notable surge in popularity from the late 1980s onwards, with peaks in the mid-1990s and early 2000s, and again around 2014."
