All the Quinns I know spelled likethat are male but I know two Kwynn's that are female and spelled like that.
Quinn is a surname and sounds masculine to me. It may be Scotch/Irish in nature, but not as a given name. I think a PP had a point. It may be the trend to give girls masculine names now, but little girls don't, in general, like to be mistaken as boys.
My sister's name is Michalea. (Spelt different from the list). I, personally, love her name but that is probably because I love her.

I also have always liked the name Aidan. I am happy to see none of my kids names are on that list! Whew. But honestly, I have received more than one comment about my son's name. (Seamus). People love it or hate it. I love it and my husband is from Ireland, so....all 4
"
\kids have Irish names.

Poor kid gets called SEE-MUS all the time though. (It is pronounced SHAY-MUS). I say that several times a month. Lol
Michaela is a lovely name. The problem is that it has been ruined by all the "Makayla" "McKayla" variations. Aidan is also lovely, but just so over used.
Yes I did name my dd Bronwyn. While it may be uncommon here go over to the UK or Australia and it is quite common. It is a traditional Welsh name, nothing made up at all.
I love Bronwyn. Different without being made up and easy to pronounce
Now I will share this again... my oldest daughter (14) has a very "unique" name. ie: made up. Now before everyone pounces I will explain again that she is adopted. She was an older adoption. Her adoption was finalized when she was 5, so changing her name was not an option. Her name has a "y" a "z" and an "h." I will not post her actual name because it is so unusual that a google search will send you right to her facebook page.
At 14 she is used to it, but it was very frustrating as a younger child to constantly have her name mispronounced. The rest of my kids have "legit" names using the common spellings. My youngest son has an uncommon, but legit, name, but it is spelled exactly as it is pronounced.
My advice to those that are choosing "different" names for their kids is to remember that this child has to live with this name. You may think it makes your kid unique or a stand-out, but that is not always a good thing. Whether intended, or not, the name also reflects on the kid. When a kid (or an adult) has a ridiculous name very few people who comment on that name stop to think that that person had no control over what they were named.
As others have said stop and think what that name will look like on a 40 year old professional man/woman.
...and as for the, "I can't imagine them being named anything else..." thing that is true not because you associate you child with that name, but because you associate that name with your child.
