Mathius is of Latin origin and means 'gift of God'. It is a variant spelling of Matthew, which was brought to Britain by the Normans during the late 11th century. Mathius gained popularity in the Middle Ages but has since become less common, giving it a somewhat vintage charm today.
"The name Mathius experienced fluctuations in popularity over the years, with peaks of 17 births in 2009 and 14 births in 2019, but generally maintained a steady average around 10 births per year from 2003 to 2023."
