Since the mods are hemming and hawing about posting what I wrote earlier, I will modify it slightly to take out what might be questionable.
Loyal – that would be a tremendous loss to the gene pool, then. My ancestor Alvina bas Miriam bas Rashi (also daughter of the Rivan) taught halacha and minhagim to her cousin the Ri m’Dampierre. Her cousin Chana bas Yocheved was quoted by Rabeinu Tam, her brother. later, R’Yosef Hagodol Treivish’s wife was well known for her insights in gemoro. Another ancestor, Mriam Spira/Luria, is described by both R’Yochanan Luria and R’Yoselin of Rosheim as giving gemoro shiurim from behind the mechitzah. Rebetzin Bayla Falk, daughter of R’Yiroel Idelish, was described as learned and a bas Torah by rabonim of the day. The grandaughter of the Maharal, who was also the grandmother of the Chavas Yoir, Chava Bacharach is described in Chavas Yoir as a boki in halocho, an excellent teacher, and an expert on Rashi and Targum.
These are only a few examples. There is no reason to denigrate their devotion to Torah. What was clearly and evidently not only allowed but encouraged by many rishonim and achronim should be praised.
And as for shiduchim, I am proud to bear the lineage of many of these women. So are my sons and daughters.
