Too much Remadora age gap of 13 years, but then....

I just realised, that if Bill Weasley was born in 1970, and Fleur was around 18 when she went to the Triwizard Tournament in 1994/5...

Bill was 6/7 years older than Fleur.

And I realised just now...

I mean, not bad for the ages of that time, and they had three children, so they would be average, Remadora would be a bit slighter older than the normal.
