Family is very important to my FI and me, and we wanted to honor our loved ones who have passed away. We've talked to both our families and we have their blessing. My godmother and his godmother (or godfather if his godmother can't make it) will be given a certain number of white roses. After the ceremony they will present them to me, and I will then put them on a table with pictures of our grandparents and uncles who have passed. Then during the reception after the major dances the DJ is going to play "Wind Beneath My Wings" and no one will be allowed on the dance floor.
I had hoped my Nana would be around to see me get married, but she passed back in October. I know she'll be there though, along with my Pop-Pop who passed almost 7 years ago.
