Help on invitation wording please!

Ok, So here's the story

My parents are not divorced and are the one's hosting the wedding, BUT my FH (Alex) parents have been divorced for years now. His father remarried when he was just a kid and his mom just recently (like 3 years ago) married someone. His mom (Sandra) and his step dad (Tony) are paying for the flowers and the the favors (like $5,500 total) while my parents are paying everything else (like $50,000).

Alex's dad (Julio) lives in Brazil and although they never see each other, him and his family over there will get invites and they will be offended if if Alex's dad's name isn't on it. But since Alex's mom and step dad are helping to pay, they should be on the invite too (although since it's a small amount they are contributing, I wouldn't say they are hosting the party)

Any suggestions on wording?

We have all three sets of parents listed on the invitation. My dad & stepmom are paying majority my mom, stepdad and his mom are contributing equally and FH and I are also contributing. I am putting all three sets of parents at the top. Mine will read:


Mr and Mrs. Dad Stepmom
Mr and Mrs Mom Stepdad
and
Mrs. FH's Mom
Would be honored to have you share in the joy
of the marriage of thier children
Stacy
and
Paul
Sunday, the twenty eighth of June
two thousand and nine
at five o'clock
The Royalton Mansion
Roslyn, New York

You might prefer:

Mr. and Mrs. Brides Mom
would be .........
...........
of the marriage of their children
Jane
and
Mike
son of
Mr. and Mrs. FH's Mom
Mr. and Mrs. FH's Dad

Put his mom first. The printers might also be able to help you with this.
