luffy = yes we will certainly see them zoro= maybe one day in a flashback we find out his father was aswordsmen to who left him and his mother alone and he died fighting mihawk to the death and his mother died too. nami=her parents where probably destroyed by the marines in a buster call (yes she was saved by bellemere during a buster call, that is why she didn't return to the marines but to her home) Usopp= doesn't have siblings, all of them are only child's so far we know. Sanji: was probably abandoned for having such a weird face. The marines took him in. Chopper: thar herd diserves to be mounted on my wall somewhere. Robin: her father might be a wg employee or he was a ponyglyph researcher too and killed right after her birth. Franky: his father left him on w7 for his own safety because he was heading into the NW with his pirate crew. Brook (don't miss write his name): was part of some kingdom's army and was 38 when he died however 50 years later his parents are probably death. Jinbe: what where his parents like?

ps: these are all theories.
