I thought I should introduce the characters before I get too deep in this story:
J-Me: Leroy Jethro Gibbs II (Gibbs and Shannon's grandson, brother of Faith and Hope, only son of Kelly Gibbs and Marcus White.)
Faith: Faith Gibbs. (Gibbs and Shannon's granddaughter, twin to Hope, sister to J-Me, oldest daughter of Kelly Gibbs and Marcus White.)
Hope: Hope Gibbs. (Gibbs and Shannon's granddaughter, twin to Faith, sister to J-Me, middle child of Kelly Gibbs and Marcus White.)
Marcus white: Marcus White. (Husband of Kelly Gibbs, father of Hope, Faith, and J-Me, Marine drill sergeant.)
TJ: Anthony DiNozzo III. (Only son of Ziva David and Anthony DiNozzo II.)
Mini: Talia Hope Faith Caitlyn David. (Only daughter of Ziva David and Anthony DiNozzo.)
Em: Emerson Sciuto. (Only daughter of Timothy McGee and Abby Scuito.)
Gus: Augustus McGee. (Only son of Timothy McGee and Abby Scuito.)
Victoria: Victoria Palmer. (Only daughter of James and Breena Palmer; for now.)
They're all like cousins since Gibbs is the main man and all grandfatherly and stuff :P
