My venue wants to know who is escorting the grandparents and mothers down the aisle. Who usually does that? We're not having "ushers" per se, but the groomsmen are lining up with the groom before the ceremony begins so I guess in theory they could do this. Couldn't the grandparents escort themselves? I have never paid attention at this part of the ceremony of the weddings I've attended so I have no idea how it normally works. I didn't even realize that grandparents and the mothers were part of the actual "processional"
