Two years? I think you'll need to check your numbers.

Wendy was 12 when she joined FT, which was seven years after the Dragons' disappearance. That'd put her at five years when Grandeeney left her, not two. And Lisanna died two years prior to the story's beginning (at which point the Dragons were gone for five years alreay), so I don't see where Lisanna's grave comes in.

When Natsu asked them if their Dragons disappeared in X777 they said "something like that, yes" before claiming to have killed them. Since they didn't dispute the date, it's likely that they killed their parents around the same year that the other Dragons went into hiding. Sting only started to idolize Natsu in absence of another father figues, so to say and Rogue only after he met Gajeel in Phantom Lord.

As to their ages, with them currently being 19 (according to their guild cards) minus the timeskip, Sting and Rogue were born in the same year as Wendy, only that they aged throughout those seven years, while Wendy was frozen.

Apart from the bit with Freed's rune-barrier there is nothing "wibbly wabbly timey wimey" going on.
