Male Pen Names

Over the centuries, many female writers have adopted male or ambiguous pen names, often to be more accepted by male readers. I'm sure this is nowhere near a comprehensive list, but I do find it fascinating what names they chose for themselves. Some were family names or after other namesakes, but others, who knows? (fun fact: all three Georges listed were writing around the same time)
Some of these are much more well-known today than others, of course, or only used a pseudonym for one or two works (I had no idea Pearl S. Buck used a male name for a few novels. I wonder why?)
