no list them twice..
technically.. your last name doesn''t even go where you are putting it if the parents are doing the inviting..
It would be
Mr and Mrs Bob Smith (your parents)
and
Mr and Mrs George Smith (his parents)
invite you to the marriage of thier children
Jane Elizabeth
to
John Joseph
(no last names.. jsut first and middle)
thats the proper wording for an invite anyway.. and it doesn''t seem as obvious that your names are the same.
Thanks ya'll....I just realized, I dont need to list them!! we'll just list our first names since the last names will already be listed via our parents! Sweet! This was one quickly solved problem.
