I did a similar thing.
Walter originally is Germanic, but I inherited it through a long English line. Hamer has been traced back to a place in England too. The combination Walter Hamer is seen in my family in generational jumps - at least 4 Walter Hamers have a grandfather with that name (myself included).
This… is freaking awesome.
Well as i keep reading others i thought i better tell mine.
Myn is one that i have used for years. No idea how long ago. I playe(d) the clarinet (need to get back into it) and i out that in as a username and it gave me options. I chose 303. I have used this and mixtures of this and others ever since. Yay! Lol. I did it without thinking when i first came on diatribe and i have no idea how to change it. 
Lol. Real exciting. 
Mine’s from the heroine of the story of Tam Lin. I’ve always liked the contrast with fairy tales where the woman is the one in need of rescuing, here Janet is the one saving the boy. And she does it by clinging to him no matter what the fae turned him into, no matter how much it hurt or scared her. True love is worth hanging onto, even through the rough parts. </hopeless romantic>

Okashii.
I love that story. 
Neimh-aille. Two gaelic words put together to create a stuntfighting character way back in 99. At the time I was in a stuntfighting gym and was going to use it.
So being Gaelic is is not pronounced the way it looks. And I forget where the accent should be. Neev-elle or close to.
