Dwarf women debate solved?

But it still says "in voice and appearance". The only thing it actually implies is that they were usually dressed differently. Is that to say they did or didn't put on false beards when they went traveling? In mythology there are no dwarf women, period. When they're mentioned, mysteriously they always have sons but no wives or daughters. They were said to have been created from maggots, but even the giants had women so you'd think the dwarves would have them too.
