I've been thinking of names for most of my life. When I was five-ish, I started getting kids I met on the playground to call me Rex because it was super-masculine. I like the name, but it's not very me. I used to fall asleep at night thinking of names for myself and I really liked Kevin ("gentle/lovable") and Zephyr (means "West wind") for a while, but I know several kids named Kevin and I would have to explain Zephyr too much.
I love names, and meanings are big for me. Because my female name is spelled uniquely (Kathryne) I wanted my male name to be spelled a little differently as well. When I heard Greg, I fell in love. It means "watchful/vigilant" so it fits me perfectly, not to mention that one of my favourite famous people is called Greg. A quick change, and viola! Greggory was born.
My last name is constantly being misspelled and mispronounced (plus it doesn't sound good with Gregg and I've never really liked it), but my mother's maiden name- Armstrong- is rather common, sounds good, and it's a nice tribute as she died when I was ten.
Lastly, my middle name. I wanted to go with Danger merely because it sounded cool, Austin Powers (need I say more?), and it's the middle name of my idol's son (Jakob). Coincidentally, my idol also has the last name Armstrong. Greggory Danger Armstrong sounded good to me at first, but Danger sounded cheesy. I like the middle initial of D. a lot, and it didn't take long for a middle name to fall into my lap. It clicked instantly, and I couldn't think of anything I like better.
Gregg(ory) Dean Armstrong just sounds perfect to me.
