Yeah, a whole family would be something to see. I've always wanted to see my friend's family, but never had the occasion. I think they are three NTs in that bunch by the way she talks about them. Her dad is an architect and very NT-like (I've met him once). Her little brother might sound like one too, although he might be SP, I find them similar sometimes. Her sister and mother are probably NFs or SJs. She says her mother is very religious so that might mean NF if she believes from the heart, or SJ if she kind of does it out of tradition and duty. Can't tell. But she is not alone as INTP.
