My FIs mother passed away 10 years ago and his dad has been remarried for 4. FI wants the invitations to read 'son of Mr & Mrs Joe Smith' and not mention his stepmom. I don't think this is right, and that it should be something like 'son of Mr and Mrs Joe Smith and stepson of Mrs. Smith'. Another thing I was thinking is to leave his parents off of the invitation completely, since my parents are technically 'hosting' the event and just have 'Mr and Mrs Jones invite you to to..." Any other ideas?!
In lieu of favors for our guests, we are making a donation to a breast cancer organization and will have cards printed honoring his late mother, so her memory will still be included (for a lack of better words...?)
