I believe that this is the Unknown Brother of Arthur Weasley who was married and has one child. --Danniesen June 14 2010 16:06
It´s likely, but unconfirmed.--Rodolphus 14:09, June 14, 2010 (UTC)
arthur´s brothes in the wedding?may be the brother of Arthur because of the appearance and age.
This individual is also on a page titled Arthur's Nephew
I suggest calling him : Drunken Uncle of Ron's at the Wedding because that is all we know about him
