I've only posted on this board a handful of times, but you girls always have good feedback and I really need your help. I'll try to make this concise:
FI and I have no living biological grandparents. FI's last living grandparent, his grandfather died a little over a year ago. FI's grandparents got divorced before FI was even born, and FI's grandfather had been re-married to Sue for over 30 years. Sue has always been a part of FI's life, and FI has just always called her by her first name (not Grandma, or any type of name like that). Since FI's mom was an adult when they got married, she never referred to Sue as her "stepmom".
Here's where the dilemma comes in. We are going to have Sue be seated at the wedding before the mothers are seated. Here's my question. In the program, should we list her as Grandmother of the Groom? Because FI's other grandmothers are deceased, we wouldn't have to worry about someone being offended. For some reason I think it's weird for her to be listed on the program as "Step Grandmother of the Groom", even though that's exactly what she is. I asked FI how he wanted her listed and he said he didn't know, and when I asked FMIL, she said it was up to FI and me.
Please let me know what you all think.

i agree with this.
however: if no one will be offended, and he feels as if she is his grandmother, then it shouldn't be a problem to call her such. since she's the only remaining one.
for fi's mom and stepdad, we're just calling them his parents, since they are the ones who raised him from like age 3.
Thanks ladies. I have really been stressing over this and last night I told FI that he has to make a decision on this. He chose "Grandmother of the Groom".
