Because you wouldn't say the same thing to a friend you haven't seen in five years as you would to your favorite potential sister-in-law, right? Family is everything in the South. This type of greeting is a great place to start when writing a wedding card for a new family member, and it's best to follow it up with something special.
"I feel very fortunate to have received another sister, cousin, or aunt."
"Thank you for allowing us to partake in the festivities. "Welcome to the clan!"
"We're overjoyed that [name] has discovered "The One," and that it is you!"
"We've added another family member to the tree today, and we're overjoyed."
"From your new family in [location], sending love and hugs always."
"Wishing you both all the happiness and love in the world." "Here's to you!" says the narrator.
"We are overjoyed to have you as part of our family. Thank you for letting us be a part of the Big Day."
"Our family has gained an incredible man/lady. "We're in luck!"
"Welcome to the family and congratulations!"
"From the beginning, you've felt like a member of the family. We're overjoyed that it's finally official!"
