My husband used to work with a woman who got pregnant at the same time as us. She had a boy, we had a girl. She picked a name that at first I hated. Now, 2 years later, I am pregnant again, and am having a boy. I now [name]LOVE[/name] the name she chose. It’s a little out there, and I really want to use it, but I don’t want to deal with any hurt feelings over using the same name. We have only run into her once since my husband left that job, however I have her on facebook and at times comment back and forth with her. We have never had a play date, and don’t ever get together. What should I do?!
What is the name? Maybe we could suggest something with similar sound/feel?
Talk to her. If it’s a name that’s not that common, she’ll notice. I can’t say whether she would be territorial about it or not, I would just send her a message on Facebook, “Hey, we’re pregnant again and are seriously considering [[name]Gabriel[/name]]” (or whatever the name is. [name]Gabriel[/name]'s obviously not that out there, haha). “We don’t want to step on any toes, but we really love this name…” etc. 
You’ll never know until you ask.
You sound more like acquaintances than friends, so I’m saying yes. Unless it’s a close friend or someone you see regularly I think it’s ok.
I personally wouldn’t have a problem with it, considering you’re not good friends and don’t spend time together. It might be nice to give her a “heads up,” if you want, but there’s no need to get her approval.
Personally, I would find another name or use a variation if you already feel like it’s going to be a problem. There are so many other wonderful names out there. But, if you find that you can’t let go, I would suggest communicating with her stating that her son’s name has been inspiring, and maybe some reasons why you like it. If it were me, I’d be flattered. However, it might not go so well. Tough choice.
I would say talk to her and ask or delete her from your friend account, LOL. It depends how important the name is to her. If your husband doesn’t work there anymore it shouldn’t matter. I am sure she wouldn’t care. If you never see her. I would just use it. LOL
I think it depends on if you consider her to be a friend or acquaintance. From what it sounds like I don’t think it would be crossing the line but it also depends on how unique the name really is.
It depends how common it is, and how likely the name is to be associated with her son. Two little boys named [name]Daniel[/name] won’t raise any eyebrows whatosever; two called [name]Xerxes[/name] would.
Again, you don’t sound particularly close. It would really have to be a one-of-a-kind name to make any waves.
I wouldn’t describe us as “friends”, no, but I do like her, which is why I’m concerned how this will go over. I personally wouldn’t mind someone using my children’s names which happen to be on the more unique side. This boys name also happens to be rather unique, and I haven’t found any success in finding a replacement name, even on here. 
Why does this have to be so hard? LOL
If we can find a cute name that ends in [name]Lux[/name]…
Is it [name]Pollux[/name]?
Yes, we really like that name a lot…
Otherwise:
[name]Calix[/name]
Delacroix
Abrax
[name]Eryx[/name]
[name]Mannix[/name]
[name]Castor[/name]? [name]Pollux[/name]'s brother?
If it makes you feel better, every time I see ‘[name]Pollux[/name]’ I think of a combination of “bollocks” and “pox.”
[name]Do[/name] you like the sound, the mythological vibe, or both?
If both-- [name]Eryx[/name] (a son of [name]Poseidon[/name]) and [name]Calix[/name]/Calyx (the founder-king of Cilicia) might be for you.
I appreciate the suggestions, but so far none of them have that “YES THAT’S IT” appeal. Maybe if it had an “o” in it…
I’m not sure what it is about the name. I’ve been crushing on it hardcore. What should my response be if the other mother is not so enthused with us using the name?
If anyone is good at making up names, something with an O and that ends in [name]Lux[/name] would be great. I’m not very good at that sort of thing. I always end up sounding like I’m creating names for D&D lol.
I’m sorry to say this, but if you worry this much you consider her a friend and cannot use the name.
Hyperion
[name]Onyx[/name]
Vercingetroix (too out there?)
I think [name]Pollux[/name] is simply far too unusual for you to borrow it and not expect hurt feelings. Your friend likely chose it in part because she wanted it to be ultra-unique.
It seems like you’re drawn to its spelling and sounds more than its meaning/literary history.
[name]Do[/name] you like Anxo? It’s the Galician from of "[name]Angelo[/name],’ meaning ‘angel.’
Exton (place-name, meaning ‘town on the [name]River[/name] Exe’)
Mattox (much less common variant of [name]Maddox[/name])
Roxas (etymology unclear, very rare surname)
