“parent mask”
Is there a function in After Effects masks that allows me to Parent the keyframing of one Mask to other Masks like one would when parenting layers to other layers?
Basically I am asking if I can control Mask animations thru animating only one Mask thats on a layer with multiple masks.

Well although you cannot really do anything to shapes contours of a mask, you can keyframe a masks expansion and feathering. Basically i playing with manipulating copied paths from Illustrator CS2s “Live Tracing” feature which has given me a lot of paths, a lot more then I would of create manually since it is analizing a vectorized color bitmap image.
I then copy pasted these paths into After Effects which interprets them as masks on a solid layer and lots of them.
So to my original question starts at this point where I have all these masks on a solid layer that make up this image I originally Live traced in Illustrator from a bitmap. Now I want to Key frame all the masks Expansion and Feathering but instead of “Select All Masks” I was wondering if I could parent all my masks from one Masks’ Key Frames. “Parent Mask”

No. You can only parent layers to each other.
But you can use expressions. Pickwhip a “follower” mask’s properties to the “leader” mask’s properties. Select the property that now has the expression, select edit>copy expression only, then select the remaining masks and select edit>paste.
That should do it.
