There are four combos. Each combo must be altered in one of four ways - by keeping the first name and changing the middle, by changing the first name and keeping the middle, by keeping the initials and changing both names, or by switching the names around. Each Keep/Change alteration can only be used once - in other words, you have to use all four so that each combo gets changed in a different way.
Good Example:
Person 1
Sara PaulineAuralie
GraceTalia SimoneJemima Lily
Person 2
Sierra Paige (kept initials)
Auralie
Renata (kept fn)
Simone Talia (switched)
Freya Lily (kept mn)
Bad Example:
Person 1
Sara PaulineAuralie
GraceTalia SimoneJemima Lily
Person 2
Samara Poppy (kept initials)
Ava Giselle (kept initials)
Simone Talia (switched)
Lily Jemima (switched)
Remember every combo gets a different Keep/Change alteration. The alterations don't have to be used in any particular order. Now, the real list:
