My parents would like to recognize my fiance's parents on the invitation. However, my fiance's dad is recently remarried (within the past year). We weren't sure if we had to name his stepmom AND biological mom on the invite, or if we should just include his mom since his dad hasn't been married for very long. For example, would the wording be:
Mr. and Mrs. John Smith
and
Ms. Jane Doe
OR just
Mr. John Smith
and
Ms. Jane Doe
Your help is very much appreciated as we don't want to offend anyone!
