I dont think the solution is to get rid of mothers or fathers. Our parents want the best for us and can get carried away with doing research. I think that parents need to be more objective and look at the whole picture instead of nitpicking. What someone’s aunts and uncles do for a living, or where their grandparents came from, should not even be in the discussion of shidduchim.
All my siblings and myself, we all got married pretty young, and I would like to give a tremendous amount of credit to my parents for being supportive of our decisions, doing research that was nogeiah to the boy directly (age, his plans for future, what he is currently doing, his level of hashkafa, a bit about his personality, what he is looking for, a bit about his immediate family..) and calling a few references. As the shidduch would progress, they would call references again or go through the shadchan to clarify some issues.
And left the rest up to Hashem!
As every married/divorced person can tell you, you always learn something new (many new things) about your spouse after you get married that you did not know before.
