It's best to let your wedding photographer know at least a week before your wedding how many family group photos want to have taken on your wedding day. Here's an easy PDF template that provides you with a standard list you can give to your photographer (fill in the first names of each person in every group).
Hey, I am Nadin! (same as "Nadine" - just without the "e"). I am a wedding photographer in Edinburgh, Scotland, specialising in big family weddings in Edinburgh, Scotland, and internationally. I have photographed so many weddings, and it is my mission to help couples with planning their dream wedding. Any questions I come across repeatedly - either in person or online, I will pop in here and provide more insight.
I hope you will find them useful :)
