what works best with a double barreled surname?

We are due in July and don't know what sex the baby is, we have some names on a short list but cannot agree on which type of name sounds better with our surname.
Our Surname is H...well- Jones.
Should we have 1, 2, 3 or 4 syllable first names is what I am getting here..
I personally like the sound of 3 syllables but wonder if it makes it too much of a mouthful?
Hubby likes short punchy 1 syllable names.
Examples of some of the names we like are:
Delilah
Cordelia
Rhett
Cohen
Sterling
Lula
Lila
Orson

Any thoughts, help suggestions greatly appreciated- we are going round in circles here! :)

Some people may say to keep the first name short but I don't necessarily agree.

I love the name Delilah, and I think that it would flow well with your surname, it can also be shortened to Lila that I see is also on your list.
I think Cordelia may be a bit to much of a mouthful - being 4 syllables, maybe it is just that I don't like the name to much, sorry.

I like Cohen and Orson best out of your boys names... I think that all of them would flow nicely with your surname though.

Good luck deciding :D.

ETA: I might add, I am not the best person to ask, I prefer longer names for first names, both my girls have 3 syllables for their first names.

I think any length name would work.

Freda Hxxwell-Jones
Lucinda Hxxwell-Jones
Max Hxxwell-Jones
Maximillion Hxxwell-Jones

All sounds pretty good to me.

I may go with something like Lucinda or Maximillion, so your DH can have Luce and Max whereas they can have nice "big" names when they're older if they want.

i'd go for a two syllable name with a double-barrelled surname.

I think one syllable names dont go well in general.
