I badly need a timeline of the next gen.

When were the following people born:

Ted Lupin (1998?)
James Potter II
Albus Potter
Lily Potter
Rose Weasley
Hugo Weasley
Victoire Weasley (May 2nd 1999?)
Dominique Weasley
Louis Weasley
Molly Weasley II
Lucy Weasley
Fred Weasley II
Roxanne Weasley
Scorpius Malfoy

I know that we don't really have canon knowledge of most of their birthdays, but os there anything we can make out from details in interviews or canon facts?

Also, do we know when Victoire and Teddy started dating?

Thank you so much, I checked the Harry Potter Lexicon, but couldn't find ANYTHING related to Post-Hogwarts. >.>
