She is consistent in giving her place of birth as Carmarthen, so that seems to rule out the one in St Clears, daughter of David & Jane. Also, amongst their children no David or Jane.
The 1808 baptism has father Samuel, no Samuel amongst their children.
Have you found baptisms for all their children? Only one I've spotted so far is for Handel. If not, it could be that they were non-conformist, or at least Charlotte was. Not all baptisms are online, particularly non-conformist ones.
