For this game, there are 10 themed sibsets you have to make, and 10 different types of sibsets. Some are larger than others, some are all one gender, some are mixed. Your job is to assign each of the themes to a different combination of siblings and then come up with names for them. For example, the first theme is Floral or Nature Names. Let's say you love floral names for girls but can't think of a nature name you like for boys. Then you might choose the 3 Girls sibset for that one. I'll post an example to clarify.
Sibset Themes
1. Floral or Nature Names
2. Names from Literature
3. Names with Same/Similar Meanings
4. Names That Begin with the Same Letter
5. Names That End with the Same Letter
6. Names with the Same Origins
7. Destination / Place Names
8. Surnames as First Names
9. Names That Are Also Words
10. Your Choice of Theme
Sibset Types
1. 2 Boys
2. 2 Girls
3. 1 Boy, 1 Girl
4. 2 Boys, 1 Girl
5. 2 Girls, 1 Boy
6. 3 Boys
7. 3 Girls
8. 2 Boys, 2 Girls
9. 3 Boys, 1 Girl
10. 3 Girls, 1 Boy
My Example:
Floral/Nature Names + 3 Girls = Lily, Brooke, & Iris
Names from Literature + 3 Boys, 1 Girl = James, Nolan, Eliot, & Phoebe
Names with Same/Similar Meanings + 1 Boy, 1 Girl = Theodore & Jane
Names that Begin with the Same Letter + 2 Boys = Harvey & Hugh
Names that End with the Same Letter + 2 Girls, 1 Boy = Gemma, Annika, & Luca
Names with the Same Origins + 2 Boys, 1 Girl = Connor, Finn, & Maeve
Destination / Place Names + 2 Boys, 2 Girls = Adelaide, Charlotte, Nile, & Hudson
Surnames as First Names + 3 Boys = Bennett, Grayson, & Jackson
Names That Are Also Words + 2 Girls = Paige & Noelle
Your Choice of Theme (3 Syllables, Last Letter of Name -> First Letter of Next Name) + 3 Girls, 1 Boy = Abigail, Lillian, Natalie, & Ellery
Hope this makes sense!
