Her origins are unknown but the Johnson rumour seems more prevalent - with her being the daughter of a barber, although the name Johnson AND the name Amis both seem to be tied to this occupation. Her origins are not the only thing obscured, it seems that she may have taken on a complete new identity at some point.
According to wikipedia, her aliases include Ann Behn, Mrs. Bean, Agent 160 and Astrea. Her husband, a possible Johann/Johan/John Behn, was out of the picture around 1664, which also seems to be the year they may have married. From this point on she went primarily by Mrs. Behn.
She became a notable, though risquee playwright and novel authoress.
She is buried at Westminster Abbey in East Cloister.
