Juden is of German origin, meaning 'of Judea' or 'Jewish'. It was initially used as a term for someone from Judah or Israel, but over time it evolved into a given name. Juden is quite uncommon today, and is more likely to be found in historical records than in current usage.
"The name Juden has seen a consistent presence with six births each year from 2011 to 2016, followed by a slight increase to seven births in 2017 and then declining to five in 2018, summing up to a total of thirty births over these years."
