请教canons 应该怎么翻译？我是从英文的简介翻译来的。

According to the legend, one of the canons living in the monastery fell in love with an Estonian maiden during one of his walks outside the castle. She declared her love back to the canon, so in order to be together, the canon brought her secretly to live with him in the castle. She was dressed as a choir boy all the time so nobody else would discover her real identity, which would be fatal for both of them. The plan worked for the lovers for a long time, as nobody bothered to doubt the gender of the new choir boy.
