Would the woman's line being a strong pedigree not be a reason to avoid such marriages? After all, any children of such a marriage belong to the mother's house so the man's house would not benefit from the pedigree at all whereas their rival would.
Right, yes. (Sorry, I probably shouldn't be answering questions before lunchtime.) Though "avoid" is strong; it's not as though every other house is such a rival that household matriarchs try to actively avoid giving children to households they're forming marriage alliances with.
