I think they have the same mother; maybe Peter was five (or some other age idk) when his mother married Rumple's father and gave birth to Rumple? Rumple looked up to Peter and Peter loved Rumple, even though he hated Rumple's father. But then something happened that turned them against each other.

I do keep thinking they might be brothers, but the way Peter said, "Like your wife, Milah... Even your own father." suggests that at least, Rumple's father isn't Peter's.
