Yes, I'm sure!

The GC is born a 5-year-old and isn't nursed by its mother. You didn't say how you know that the GC was born in your game. Did you get a message announcing the birth (followed by the gathering in Village Center)? If so, then another GC won't be born.

There is a bug in v1.0 that can cause villagers to disappear under certain circumstances. That bug was the main reason that v1.1 was developed and released. Once a villager has disappeared, there is no way to retrieve them, apart from the normal data backup and recovery techniques available on the Palm platform.
