Reuben

Reuben or Reuven is a Biblical male first name from Hebrew רְאוּבֵן (Re'uven), meaning "behold, a son". In the Bible, Reuben was the firstborn son of Jacob.

Variants include Reuvein in Yiddish or as an English variant spelling on the Hebrew original; Rúben in European Portuguese; Rubens in Brazilian Portuguese; Rubén in Spanish; Rubèn in Catalan; Ruben in Dutch, German, French, Italian, Indonesian, Polish, Swedish, Norwegian, Danish, and Armenian; and Rupen/Roupen in Western Armenian.

The form Ruben can also be a form of the name Robin, itself a variation of the Germanic name Robert, in several Celtic languages. It preserves the "u" sound from the name's first component "hruod" (compare Ruairí, the Irish form of Roderick). Provided by Wikipedia
