My FI mom was married three times. Her current husband, then the man my FiIcalls "dad" was the man who raised him and then there's his biological father. So that's 3 fathers on his side and their wives. My parents are still married. So my question is how should we have everyone walk down the aisle? I have never been to a catholic wedding so I'm totally unfamiliar with how this works. We would like to include everyone as they all mean so much to the both of us. Any thoughts?
