Cutie Mark Names

[C.C. 66]

I have been wondering since the first day I became a pegasister how the parents of ponies know how to name their children after their cutie marks and such, and in Hearth's Warming Eve I realized that the ponies from long ago were not really named after their cutie marks. And from the very start it seems that the ponies knew something about their young's future or something because Celestia was named after the sun and Luna the moon, and they are years older than the ponies in Twi's generation. And Starswirl was named after his magical abilities even when he was (this is gonna make me sound rude) really old. So how the heck to the parents know their child's cutie mark, or is it just a lucky guess?
