Maybe they would be a little sceptical and might prefer her to marry a muggle as that is the world they know, and they, might fear her becoming even more detatched from them if she starts a family of her own.

But on the other hand if Hermionie has told them alot about Harry she must have told them alot about Ron, and they might be quite pleased that she is choosing a wizard who has fought alongside Harry for the rights and freedoms of muggles and muggleborns. So if she does choose to marry a wizard, somebody like Ron would be the most agreeable choice.
