Another option nobody is considering is that perhaps Ruby names her weapons for her ancestors. So, she could indeed by Ruby Rose, with Summer Rose being her grandmother (selected as the obvious from Little Red Riding Hood). Then, Crimson Rose could be her mother, whom she named her scythe for in memory of. Or, it could be a sister who died.

A more grim take on this would be that the weapon actually has the soul of her relative in it, so she's not naming the scythe to honor them, but because that is what they are now.
