Help! We're putting the programs together, and can't think of what to call the woman who is acting as FH's mother on the day. She's a very close friend of the family, and really stepped in for him after his mother passed away. They're very explicitly not religious and she does not want to be listed as a "Godmother."
Any ideas on what we can call her? "Special Friend" seems awkward, and "Fulfilling the Duties of Mother of the Groom" or "Serving as Mother of the Groom" sound both awkward and pretentious.
Thanks!
