That, is, if you accept Julia as July. 
Another tangent…my mom went to school with a girl named Mary Christmas (seriously, I saw it moms yearbook) and I went to school with a girl named Sunny Holiday.
(That sounds like it’s gonna have extra iron and be good for your bowels’ health…)
Both julio/July as month and Julio as firstname derive from Caius Iulius, so I’d say they count; and for the same reason so do the Julias and Julies, and the occasional Julius (Henry Marx).
I might accept the possibility that there’s a Julius Orange out there somewhere. That surname is not all that rare.
I actually met a woman yesterday named October, before I had seen this thread. Very strange!
We came very close to naming our twins Summer and Winter - possibly as middle names but we tried them on for size as first names.
Went instead with the family tradition of ordinary first names and very unusual middle names - which can be hidden, used as a first or (particularly for girls) dropped altogether. I think it’s crippling to give kids bizarre names they can’t escape. Maybe even a little cruel.
Miraculous! Did you look right away for something to bet money on?
I see we’ve already got lots of Septembers, but there’s also a porn actress named September Corrino.
Assuming that is her real name, of course.
And according to whitepages.com, there are 12 people named December Martin in the US.
Well, I got three job interviews yesterday, so I think that counts!
That counts! Great for you.
