Looking for title or author of a book I read as a teen in the 90s. I believe it was possibly published in the 80s. It was medical science fiction with child prodigies. It was adult to young adult.
A man, (David?) looking for information about children raised in a laboratory. Possibly triplets, some advanced in art, math or technology, the others having reached a telepathic level. His father/aunt/uncle may have been a part of of the group. Possibly 3 sets of children, maybe red haired.
Australia comes to mind for some reason, could be false memory.
