Don't have much time right now to respond fully. However, looks like you're headed in the right direction. Of all the descriptions listed, Family #7 jumped out at me as stereoptypical: Asian who's fallen in with the "wrong" crowd, shoplifts (sometimes), hustles for money, and works underground on cars? Substitute any East Asian nationality there for a feel of trope.

Family #11 also strikes me as running close to trope with some points. Good at biology, etc.? Bright? Sounds quite typical.

I think the other one that stuck out was the Indian family.

Can't say more than that as unfamiliarity has now caught up with me. :P

Hope this helps some.
