Any advice on wording for listing my fiance's step-grandmother in the wedding program? She's walking in with his paternal grandfather, but is not his wife. She's the mother of his step-mother. We're listing Grandpa as "Grandfather of the Groom". Should we just change that to "Grandparents of the Groom"? Or somehow list that she's the "maternal step-grandmother". Ugh.....his step-mom just brought it up and I don't want to hurt anyone's feelings.
