I think Hilary is the only name on this list where I haven’t known a male and a female with that name. OK, and Qbert… My sister had a male buddy in school named Courtney.
I am British, and to me Aaron is air-on and Erin is eh-rin (with a short i). They sound quite distinct. However, I know many Americans (including my own children) pronounce both as something like eh-run. (I think, however, I have heard Hank Aaron’s name pronounced by Americans as ah-ron.)
Of course they are completely different names with quite different origins. Aaron is from the Old Testament, and Erin is Irish for Ireland. And, of course, to all intents, Aaron is exclusively male and Erin exclusively female. (No doubt that will be changing in America, though, as people get confused by their own poorly differentiated pronunciation.)
Is there a point to this poll, by the way? (I gave my answers upthread.)

Qbert Now you’re just being silly…
Sidney and Jamie were the only ones I had any second thoughts about.
Expanding a bit:
The only males I have ever known named Tracy, Courtney, or Robin were all born at least 40 years ago, usually 50, 60, or more. And there have been mighty few of them. But at least I have known males by these names, even if it seems they are rapidly on their way to extinction.
In contrast, I’ve known a number of females of all age ranges with these names. So in my book they are quite definitely female.
Sidney–likewise, the only men I know with the name are quite old by now. (I do know a young man named Sid, but his given name is not Sidney.) Then again, I think I only know one female Sidney, and she’s a kid. So that’s a bit of a headscratcher.
I believe I have never known a male named Shannon, Kelly, Hilary, or Jody, though I know there have been men with these names (baseball players Shannon Stewart, Kelly Gruber, and Jody Davis, illustrator Hilary Knight…). These are easy–female all the way.
I have never known, or heard of, a male named Erin. (I think.) Female, most definitely.
Seems like I’ve known a female who spelled her name Terry, though Terri has been in my experience much more common. I don’t think I’ve ever known a female who spelled her name Tony. Both definitely male.
I have known multiple Jamies of each sex, probably more males but it’s close. Same with Alex, but a lot more men than women. I went with male for both.
What say you guys to Marion?? or Stacy??

I know Alex is traditionally a male name, but there were three female Alexes in my high school class (of 100) and no male Alexes, so I usually think of one of them.
Erin is always a female name. Aaron is always a male name.

They’re all names that used to be male names and have become female names in recent decades.
Do I win a prize?
Also, the E in Erin is a schwa and the name Erin is not only pronounced in a completely different way to Aaron, they’re not even distantly related. Aaron is a biblical name that comes from Hebrew, Erin is an Irish Gaelic name. They most certainly are not different gender-versions of the same name.

No. James is a male name. Jamie can be a girls name.
I’ve heard of female Jamies being called James, but not one with the first name actually James.
ETA: And Cubert is a male name.
Robin- Girl, though the only Robin in my life is male
Terry- Girl
Kelly-Girl
Shannon-I think girl, my brother recently learned this mistake with my 13 y/o niece she told him she was going to hang out at Shannon’s house, thinking nothing of it the request was approved. My sister in law came home to point out Shannon is a 15 y/o boy who’s parents aren’t home till much later.
Tracy- Girl
