Just curious: if you saw the given name “Lindsay”, would you expect the person to be male or female? Said person is middle-aged and British, if that makes a difference.
I immediately think of Lindsay Wagner (because I’m old), so I think ‘female’.
Middle Aged British, I might say male. But off the top of my head, “Lindsay Graham” is the only male Lindsay I can think of.
I thought Lindsay was originally female and Lindsey was originally male, although I can’t seem to find a cite. Several websites say that now either name can be used for a boy or a girl, indicating that there was a distinction in the past.
I’m aware that the name was originally male, but all the Lindsays I’ve met have been women.
Shit, I clicked too fast. Just Lindsay with no other information is female. Knowing it’s a middle aged Briton switches it to male in my head for some reason.
Lindsay - female
Lindsey - male
in my head at least
Female.
Male.
At least it was until a certain drug addled redhead actress became identified with the name.
I voted female because I named my daughter Lindsay, but I’ve known men by that name.
Of course, I also have an uncle named Leslie, so maybe my family just has a tenuous grasp on names and gender.
Guess I’m even older, because I read it as unisex.
I’m sorry, but using last names as first names has always struck me as bizarre. Whether for boys or girls, it makes no difference, it has a weird ring to it either way. I think it must have started as a WASP custom, because nobody had such names in the ethnic environment where I grew up.
Lindsay Buckingham 
But Lindsay Wagner was my first Lindsay, then Buckingham, so…it still seems a girlish name, but so is Leslie. And Nat is rather masculine, yet that’s MY name, so there ya go.
I would expect any given Lindsey to be female, but not be surprised if they were male. Same with Leslie, Kelly, Shannon, Jamie.
I didn’t know the spelling -ay/-ey indicated gender, that’s interesting.
The first Lindsay I ever knew was a boy, so I always associated that name with being male.
Probably female but I’d double-check to be sure. The spelling would make it much more likely, but still not definite.
If the person were British and middle-aged then I’d be even more likely to say female, because I’ve known female Lyndsays in that age group but not male.
I just met a girl Lindsay at my school… so perhaps that biases me.
But it definitely sounds female to me.
Lindsey
I dated a female Lindsay so female it is.
Similarly, in my first encounter with the name Hillary, that was a male. So it took me a long time (and years later) before Hillary seemed suitable for a female. (Not sure how spelling counted. It might have been Hilary.)
Likewise, there’s Francis (male) / Frances (female). But these might be pronounced subtly differently too:
Francis: Fran-siss.
Frances: Fran-seez.
The two women I know who are names Frances, pronounce their name exactly like the male spelling.
