Sorry I'm new to this writing story business but anyway to answer yall questions. Please bear with me i'm not perfect and best at this.
Matsuri family they do live in the sand village just her mom her dad died on some mission, they went to Konohagakure for a mission from the sand village. Then her mom died do to the attack on them by Madara. So she by herself for now.
Hinata's is an Hyuuga (Common sense) they do live in Konoha they aren't moving from there when the attack happened they were all gone some where on mission and some were running errands for the Main Branch.
Madara knew because they were rumors among the villagers from both Leaf and Sand that they were the ones who could keep the Tailed Beast at bay. Do to them being the only ones nice to them. Then the Tailed Beast fell in love with them not Naruto and Gaara yet.
I will try better please bear with me or if yall want yall can give me some tips that will help me.
