I'm seeking some suggestions on invitation wording!
The bride's family is mostly paying for the wedding, except the groom's family is paying for flowers and limos. As such, we were inclined to do a traditional wording of Mr. & Mrs. Bride's Parents request the honor of your company...
However, FMIL has made it clear that she wants her name on the invitation as well. FI's father is deceased, and his mother has remarried.
I see 2 options:
1) Mr. and Mrs. Bride's Parents request the honor of your company...at the marriage of their daughter, Bride to, Groom, SON OF MR. AND MRS. GROOM'S PARENTS NAME. I like this option, but then is it Mr. and Mrs. FI's father's name (with "the late" in front of dad's name), or is it Mr. and Mrs. FI's step-father's name (but could that offend relatives of his late father)? He is not really the "son" of his step-father, although he is very close to his stepfather.
2) Put Bride's family and Groom's family (with Mr. and Mrs. FI's Stepfather's name) request the honor of your presence....
In this scenario, we are not using the "son of" language, however, then aren't we taking away the credit from Bride's parents who are floating 98% of the wedding bill by including both sets of parents in the top heading?? I know invitation wording isn't necessarily indicative of who's paying, but I know a lot of people still believe it is.
Any other suggestions other than the 2 I mentioned? Any thoughts on which of the 2 above scenarios is more appropriate? Who knew invitation wording could be so complicated!

Thanks in advance for any suggestions!
