Parents' names on invitations

Both of my parents have passed away, but I am thinking of ways to include their memories into my wedding. Does anyone have an example of including deceased parents' names on invitations (something like...'In Memory of..'
I know this is not typical, and they can neither pay for the wedding, nor 'request the honor' on anyone's presence, but I feel like there may be a way to include them.

Thanks!

You can say:

Jane Doe
daughter of the late Bob and Ann Doe
and
Joe Blow
son of John and Jen Blow
request the honor of your presence.....
