Did your friends kids turn out to be gifted?

Yes, I'm sure some of our suspicion was due to family history. However, I suspect we also sought out information because there was an odd and confusing mix of behaviors. It was hard to know - are these sort of tricky savant behaviors or signs of something more indicating giftedness? If I read the first book I found on the subject didn't bother to discuss 2E kids or presented a list of milestones like in Ruf's book I might have been more inclined to dismiss it.

It has been a while since I read it, so correct me if I wrong, but it was not my recollection of Ruf's book that she says that one specific ability in a sea of developmental delays would still place a child at a high level of giftedness.
