I have three first cousins that are invited to our wedding. Their mother past away last year and they all still live together at the house. They are 17, 19 and 20 years old. I want to give them an invitation that lets them know they are welcome to each bring a guest. Should I send three invitations (with and Guest) or 1? If 1, how do I word it?
Also, how would I address it for two people living together, unmarried and the female as two kids? The female is a widow if that matters since she kept her husbands last name.
