I am having trouble finding a way to involve my FI 3rd sister in our wedding party. His youngest brother is ringbearer and older two are groomsmen, his best friend being his best man, two of his sisters whom i am extremely close to are my bridesmaids and my neice is my maid of honor. His 3rd sister lived both out of country and across the US the first 5 years we were dating just recently moving about an hour away. Ive only met her a handful of times at family functions. I don;t want her to be the only sibling not included because unfortunately shes always been the odd one out even as children but i don't want an uneven wedding party. We tossed around the idea of having her as an officiant but are still unsure. We are also planning on having her 4 year old daughter as one of our flower girls. Just wondered if you guys have any ideas!
