What is "innogen"

Innogen is a female character in legendary early British history being the wife of Brutus of Troy the purported 12 century BC first king of Britain. According to the legend prior to his settling in Britain, Brutus overthrew the Greek king Pandrasus and was awarded the hand in marriage of Pandrasus' daughter Innogen. The name Innogen is an evident cognate of inghean a now-obsolete Gaelic word - both Irish and Scottish - indicating daughter: likely Innogen or its equivalent appeared in early Celtic documentations of the legend of Brutus to identify her only as being the daughter of Pandrasus rather than to indicate her proper name. Innogen was a character in a lost play by Henry Chettle and John Day entitled The Conquest of Brute with the first finding of the Bath which was performed by the Lord Admiral's Men at the Rose in December 1598.

Imogen originated as a misspelling of, or variation on, Innogen.
