I have seen sample invites online in the past that started out "with joyous hearts..." and I really like that, however I also want to say "together with their families" as our parents our contributing a little. Does it sound awkward to say:
With joyous hearts
Brides Name
and
Grooms Name
Together with their families
request the pleasure of your company as they exchange vows
Wedding Date
at
Wedding location.
any other suggestions?
