Tosefta Yevamot
Rabban Shimon ben Gamaliel says, if she performs miyun, her miyun is valid. If not, she waits until she reaches adulthood and performs chalitzah, and this one goes out on account of [the prohibition against marrying] "his wife's sister." § Two brothers who married two orphans -- a minor girl and a deaf-mute. [If] the husband of the minor girl dies, the deaf-mute goes out with a divorce document, and the minor girl waits until she reaches adulthood and performs chalitzah. [If] the husband of the deaf-mute dies, the minor girl goes out with a divorce document, and the deaf-mute is forbidden forever [to remarry], but if one does come upon her, she goes out with a divorce document and she is released [to marry another man].
