Sorry, but YABU
I HATED my name growing up. I hated that my parents gave me a 'weird' name and then managed to alliterate my first and second names, thereby guaranteeing I would fall in love with and marry a man whose surname starts with the same letter (happened) and now I have to hyphenate just to have more than one letter in my monogram.
I am named after my mother
She doesn't go by it, as she and her twin both go by their middle names, and mine is spelled slightly differently to make it sound right in English.
I've met all of two other people with my name, one of them from Denmark, where my name originates. My aunts and uncles all have names that may seem 'made up' but are actually traditional family names ("Sig").
My brother has a surname-as-firstname. He was the first male child born in the family after my great-grandmother died. She only had one daughter so her grandkids agreed that the first one to have a boy would name him Davis to carry on her name.
I get loads of compliments on my name and wouldn't change it now, but when I was 7 I desperately wanted to be like everyone else. Too bad. If it hadn't been my name they would have picked on something else.
I've given my daughter an unusual name that can be shortened a couple ways to something more tradtionally English-sounding and a very traditional middle name, Rose (which unbeknownst to me was having a resurgence - thanks SATC!), because it is the national flower of both England where she was born, and the US where we are from. She has options if she wants them, but it was important to me to find a name that didn't have a passive meaning.
The names you assume are 'made up' may just be from a different culture.
Of course, adding letters is and I have to agree with this
