co-mother-in-law

Etymology
From or.

Noun

 * 1)  The mother of one's children-in-law; that is, the mother-in-law of one's children, or, the mother of one spouse in relation to the parents of the other spouse; either of two or more women whose children marry each other, such as the mother of a bride vis-à-vis the mother of the groom.

Usage notes

 * In conversation, the generic "in-law" is generally used, with context left to disambiguate. Once grandchildren are born, the term co-grandmother may be used if the focus is on the relationship through the grandchildren rather than through the married couple.
