I'm really confused about the processional order and who escorts who. We have an officiant, a groom, a BM, groom's parents (divorced), groom's grandparents, and my mother...then of course, my jr BM, MOH, me and my dad, but I know how that works. I assume you start with the grandparents, but can grandpa escort grandma? Who escorts the mothers? Where are the groom and BM at this point? I've been to a wedding where the groom kept walking up and down the aisle escorting people and it was odd.
