But other wiziarding families, like the Weasley's, would not stoop to such levels cause they feel that true love would concur all.
So you're saying that it's not an officially sanctioned method of matrimony? Then where would they be going to get their vows performed, and what prevents the ones like the Weasleys from getting divorced?

Marauderette, yes, they'd still be cousins.
