I think we're going to ignore the surname issue. Are we mean?

My first name and maiden name (which I still use at work) run into each other to make another first name and it is really annoying. People think I am called something different, use that to email me (which doesn't work of course), however much of a pause I leave when introducing myself new acquaintances always mishear, post goes missing, it is a pita.

The Rosalie thing would be enough for me to say no.

Every time she gives her name it will be taken as Rosalie and then she'll be asked her surname.
No, that's my name Rosa Lee.
Yes, I got that part. What's your surname?

Every. Single. Time.

Definitely not. I'm someone who has to spell my name every freaking time it's asked. I wouldn't give a child a name that even now you know will cause confusion. It's not about just what you like, she'll have to live with it.

Wasn't gypsy rose lee a stripper?!

I think it's a pretty name, which goes eatly with the surname, and as for it getting confused with the surname, how often do people address someone they know by their full name? There are plenty of other names out there which will make people raise their eyebrows, I don't see this as being one of them.

I wouldn't do it because of the cockney rhyming slang 'Cup of Rosie Lee. ' First thing I thought of and I'm not a Londoner.

Since you already have the issue with DD1's name even though it doesn't make a "real name", e.g. Jane Lee, but still have to explain/adapt it anyway, why not just go with Rosa Lee as you can't avoid it whatever it is...
Also, how about:
Rosetta Lee
Rosalba Lee
Rosina Lee
Rosella Lee
or to hell with it, Rosalie Lee?

I think the rhythm of a name is just as important - so with a very short surname like that I would be using a first name with at least three (or more) syllables - like Jessica Lee, Imogen Lee, Catherine Lee, etc etc!

I think it would be fine. They sound quite good together as you can round it by adding a pause. I don't see a big problem here (and I also have an annoying surname which rules out anything ending in -a, -e as well as a whole host of other names so I feel your pain).

No, no and no again. Child's name is an inherent part of her identity; she won't thank you for giving her such a ridiculous monikor. What is your DH thinking?.

Rosa is a lovely name. DD2 was going to be Rosamund, nn Rosa till DH decided he actually didn't like it . It means 'Rose of the world'

I don't see the problem with your surname either.

HorryIsUpduffed is right, so many names have the name 'leigh' bolted on to the end these days you need to make sure it's clear what the sur name is. I think if you say your name and your sur name it's fairly important that the sur name is discernible.

Rosamund Lea. I think you should put one on the bc so that occasionally she can use it. Rosemary Lee, but everybody calls me Rosa. your dh won't be the one standing there saying 'no lea is the sur name. my first name is just Rosa, no not Rosalie, Rosa Pause Lea. fgs!

cuppa rosie lea!? he's mad.

if your sur name were Murray would he use Ruby?

it's the same.

I would do it Rosa is beautiful.

I also think Rosa goes better with your surname than Charlotte although they are both lovely names.

I do not think that using Rosa is likely to lead to your child being bullied because of her name; I can't imagine that her peers would think anything of it and TBH many adults wouldn't make the possible connection with either the gypsy or tea.

My dad has a name that, when said together (firstname/surname) run into each other and can make it hard to work out where his first name ends and his surname begins : think something like Paul Ledwick could be Paul Edwick. Not quite the same issue as you are considering but he has spent 60+ years easily overcoming this by leaving a pause between his names. there must be LOADS of other people whose names also run together to lead to possible ambiguity.

I would use Rosa (and also think it goes very well with the 24th name on the ONS list.)

I also think that Roseabella is a fantastic name and could be shortened to Rosa which is also lovely.

Well, I am biased, but Rosa is a beautiful name
I didn't think of the gypsy connection and had never heard of the rhyming slang.
Just go for it. My Rosa has a surname that begins with Ro too, I'm sure that some would find it cruel but nobody has batted an eyelid in the two years since she's been born. Not that I even say her full name very often!

I have often had the problem the other way round I am X-Lee then a boring surname like Smith. People think Lee is my second name.

I've hated having a hyphenated name all my life.

I would use it. Rosa is a lovely name. I don't think it will cause her to be bullied.
