Welcome Zori^^ Don't worry, my English isn't that good either.

Luffy: I get the feeling that his mother and grandmother are dead...

Zoro: ...no idea

Nami: Bell-mere found her and Nojiko after a pirate attack, so most likely her parents died during it.

Usopp: Yasopp doesn't seem the womanizer type so I doubt that he has siblings.

Sanji: maybe his parents are alive and living in North Blue

Chopper: After all that happened between him and his family I don't want to see them meeting again.

Robin: I think her father was a famous archeologist who wanted to discover the true history, but failed while searching for clues. His will was passed down to Olvia and now to Robin.

Franky: His parents might have thrown him into the ocean because they didn't want him to live as a pirate. Or maybe they were under a marine attack and did it in order to help him escape.

Brook: obviously dead...
