Boy’s name to go with difficult surname

[Leanybean]

Hi, I need help!
We are due in around 10 weeks and are really struggling to agree on any boys’ names. DH is extremely sensitive about how names sound with the first syllable of our surname, COCHRANE.

DD is Charley - Charlotte - so it kind of needs to compliment that too.
We both liked Rafferty for a while before feeling that it is too ‘brave’ compared to Charlotte. We can’t have Jack, Jacob or Alexander, all of which we both like.
We would both really like a name that can be shortened to a nn.

Example names DH likes:
Thomas
Arthur
Raphael

Example names I like:
Maxwell
Joseph
Zachary
Finley (DH thinks could sound like ‘thin ck’)
Isaac (I agree with DH that this is inappropriate with our surname)
Oliver (DH thinks could sound like ‘I love a ck’)

What other names are there that could compliment Charlotte but don’t have any remote phallic connotation and go ok with Cochrane??!

If it is a girl we have narrowed it to either Jessica or Megan.

Thanks for your opinions!

Donquixote bit late but 🤣🤣🤣🤣 at ivanka

That's OK. Clearly I was was very subtle :-)

Hi guys,
Wow thanks for all the suggestions and good humour! Lots for us to think about and lots of new names to mull over for consideration. Never made the ‘half a’ connotation with Arthur!
Can’t believe the newspapers have picked up this thread - slow news day indeed, and some nasty comments on them about our capacity as parents that I won’t be reading any further.
We live in central England (not Scotland) and it is pronounced ‘Cock’ here - we hear innuendos constantly, which I just take to be affectionate and brush off, but we want to give our child a name that won’t cause them any reason for unnecessary problems, especially given that a boy will quite probably have that name for his whole life. Changing our surname is not personally an option for us.
Thanks again for the love and feedback guys, so appreciated!

I think it's a fine surname.

Joseph works well. Rafe is great.
