I am with Bubby B. I agree with her entire post
I have no problem with the expression “u’ra-ah-yaso” per se, but the chosson and kallah were not born in a vacuum. There is nothing inherently untznisudig in mentioning the mothers’ names. IMO in this specific isntance, it is only untzniusdig if you THINK it to be so, and I think we are going a little overboard in this, when we talk about a simple invitation (whioch does not even have a picture of the wife on it), which clearly comes from both the father AND the mother. Just my opinion. Please do not shoot the messenger.
