Invitation wording help (sorry long)

It's invitation time and FH and I need help with wording! Here is the complication - my parents are married but my mother kept her maiden name and hypenathed me and my siblings. My parents do not want to go on the invite as Mr. & Mrs.

FH's father is deceased and FH has no memories of him. FMIL has a boyfriend of about 10 years who she wants on the invitation but FH does not want him listed as part of 'son of.'

FH is close to his mother and I am close to my parents so we would like names on the invites esp since my parents are paying a portion of the hall and FMIL is paying a portion of the hall and she bought our honeymoon.

Any suggestions?

Someone suggested:

Mr. WH & Ms. LB
together with Ms. KM & Mr. JL
request the honour of your presence at the marriage of etc....

Not sure though.

Any and all suggestions are greatly appreciated!

Mrs. LB and Mr. WH
Ms. KM and Mr. JL
request the honour of your presence at the marriage of

Joan B-H

and

John M


your mother is Mrs. since she is married, regardless if she has a different last name. Then if you write yours and your fiance's last names it will be obvious who your parents are.

What about:

Together with their parents

Bride Middle Last
&
Groom Middle Last

request the honour of your presence...
