Matthis is of French origin, derived from the Latin name Matthias, which means 'gift of God'. It is a unisex name, although it's more commonly used for boys in English-speaking countries. The name Matthis gained popularity in France during the 20th century and has since spread to other European countries. In recent years, it has also started to appear in English-speaking nations.
"Matthis was quite popular in 2008 with 7 births, but saw fewer births in the subsequent years: 5 in 2015 and another 5 in 2016. Altogether, there were 17 babies named Matthis during these three years."
