Lily and James lived longer, but still died at 31, leaving not one but seven children behind. Camellia was just a baby at the time of his death, and Hortense was starting her first year at Hogwarts. The fact that there are seven Potters is not common knowledge; people just keep seeing new Potters arriving at school and are like, "???".
Yes, Harry is still the boy who lived.
The fact that all the Weasley and Potter children are lined up is just a funny coincidence.
They didn't grow up with the Dursleys because there were too many of them. But with Remus, it was a complicated time.
