Thoughts?

Sorelle is the name of a cheap clothing range - just google. It also used to be the name of cheap bubblebath etc. To my utter astonishment, examples of this brand are now being traded as vintage/antiques www.worthpoint.com/worthopedia/1960-jean-sorelle-ltd-london-sorella-493373982
The usual spelling of the name is - as pp has said - Sorrel. It's fine. It's a green herb. Very nice. Country/nature vibe. Also it tastes quite sharp and lemony - that might suggest that a child with the name would be quick-witted also.
Elspeth is really nice.
Meredith is to me a surname or boy's name (Welsh).
Courtney is another surname. It has for centuries also been a boy's name; now it just reminds me of celebs.

Lawrence, Arthur, Pascal = all good names.
Rafael is also a nice name but it seems to be having - as Mumsnetters say - rather a moment.

Girls:

Courtney - a bit chavvy
Sorrelle - sounds like a herb
Elspeth - nice, Elsie as a nickname
Meredith - old fashioned, not in a good way

Boys:
Lawrence - nice but a bit of a mouthful so will get shortened
Arthur - very popular
Rafael - are you Italian?
Pascal - are you French?

Lawrence and Elspeth (although I personally prefer the more popular Laurence spelling). Second choice Arthur and Meredith. Not keen on the others, sorry.

What an interesting mix of names!
Courtney - awful
Sorrelle - nice but agree with PP about the spelling of Sorrel
Elspeth - nice, underused
Meredith - ok, but not keen on the subsequent nn Merry

Lawrence - nice, probably due a revival along with other "old men" names
Arthur - nice but potentially overused these days?
Rafael - best kept for teenage turtles
Pascal - not unless you're a character in a french school text book

Elspeth is one of the finest names ever. Also like Meredith.

Lawrence and Arthur are both good.

Courtney - personally find it chavvy
Sorrelle - like it and unusual but would use standard spelling Sorrel
Elspeth - like it pretty
Meredith - ok

Boys:
Lawrence - ok, sweet with nn Lawrie
Arthur - love it
Rafael - ok if Spanish/Italian, not sure if UK
Pascal - ditto ok if French

Courtney is my favourite girls name on the list

Love Lawrence
So familiar yet underused. The perfect combination
