DH and I were both ID'd as GT as kids, as were his only sibling and my only sibling. There's also reason to believe that at least a couple of our parents were GT (if not all 4), though they were not tested or ID'd as such back in those days.
There are pros and cons to all that GTness in families. I think it's one of the reasons I didn't realize right away just how bright DS7 really was. MG (or higher) was the norm to us, so I just assumed DS7 was MG. His high test scores were a huge shock to me, even though I really should have known better because I'd been reading about GTness since I was a child. (My mom was the founder of a support group for parents and GT kids, so she had all the books back then. I read literally everything I could get my hands on, including her books. Back then, GT books didn't really talk about LOGs though. More reason for my cluelessness about DS7's specific situation, even though I was pretty well-versed in GTness long before I had kids...)
Finally, it turns out that most of DS7's young friends through his life have probably been MG, but at the time I had always figured they were ND and he was MG. Without a good sense of what ND looked like, my whole frame of reference skewed low.
So I would argue that in some cases, the more GTness you see, the less aware you are of GTness. It seems backwards, but I think I was a *lot* more confused and freaked out when I got here than newbies I've seen since who haven't had as much GT experience as I had. GT denial is easier to stay in--and harder to shake yourself out of!--when virtually everyone you know is GT.
If that makes any sense...
