I always wish he'd brought in a female Dwarf at some point, and maybe even some Entwives. But it's fairly clear that Galadriel carries a lot more authority than her consort.

Interesting pairing of Mary Slessor the missionary, and Mary Kingsley, who couldn't stand missionaries. I doubt very much if being a Catholic would have made Tolkien any less likely to be aware of them. We don't tend to work that way, now or then.
