Male names on females

[rubytitania.livejournal.com]

So, I was thinking about the whole trend of giving girls names which are blatantly masculine (Ryan, James etc), and I realised there are two women at my work who have men's names. I've worked there a year and a half so the names don't even sound odd to me anymore, but I remember when I started I thought it was very strange. We have a Merlin (in her 30s I think), and a Felix (probably late 40s). What do you guys think? Do you know any people with odd names which you hardly even notice because you know them?
