Invitation wording, not happy with formality.

I have the task of finding the right wording for my daughter’s invitations, she can’t look , she is so busy as it is. Info then your opinions.
1. My husband and I are hosting with finding all the vendors, paying for almost the entire wedding and reception which is in the evening, decorations, invites, to a meal with sans cocktail hour with canapés, plated dinner and dancing plus having to throw a shower ( glad the rules have relaxed on this).
2 The grooms family is graciously paying for the rehearsal dinner, grooms cake, bridal bouquet, corsages and boutonnières.
3. Groom is paying for honeymoon
I want to include the grooms parents with a line saying son of (their names). Is that ok?

Here is the part that I am not happy about, not anyone but wording. It’s the lack of well, my first name and the groom’s mother as well. It actually has nothing to do with me not getting recognition, both families know and recognize what we have been doing. It though feels old to have written out Mr. and Mrs.( mans name) last name. I like to know the modern alternatives for formality. Since it’s formal not sure if our names are suffice or if we can actually put Mr. Tim and Mrs. Robyn with last name. Opinions?
