... and if Mary's mother had carried the guilt of Original Sin, then Mary would not have been sinless. And if Mary's grandmother had carried the guilt of Original sin, then Mary's mother would not have been sinless.
You'd have to carry this line of reasoning all the way back to a sinless Eve, and we well know Eve was not sinless.
So, we accept scripture, that Jesus Christ was born of a virgin, Mary, who was herself in need of salvation, according to her own words.
Jesus Christ was sinless. Mary was not. Was she favored and even blessed? Yes, scripture tells us this. But it also tells us she was not sinless.
I do not understand the purpose of adding this Mariology as a result. It's not necessary to salvation and it's not supported by scripture.

The Catholic stance is that Mary required forgiveness of original sin because she shared blood and flesh with Christ for 9 months.
Who amongst Mary’s foremothers can claim the same?
