So before we start with the story, here's an introduction of Jelsa, Eugenzel, Kristanna and Mericcup's children. (I'm horrible at giving names so.... Sorry if they don't sound too good)

Jelsa's children are twins, one girl and one boy:
Eliza: 8 years old
Elijah: 8 years old

Eugenzel's children are two girls:
Jessica: 8 years old
Jenna: 7 years old

Kristanna's children are one girl and one boy:
Kristine: 8 years old
Kristen: 7 years old

Mericcup's children are two boys:
Harold: 8 years old
Henry: 7 years old

So all of them have two kids, age difference is only 1 year. Yeah, I know, I ain't creative at all. The names all sound alike since I really have no idea how to name the kids.
