im 20 yrs and have 9weeks to go havent decided on a name as im looking for some think unique for my unborn son?

Your help is much appreciated.

i like...

Kohen Eligh

Corren Eligh

Marley Kohen

Kohen Ryel

or i was thinking of having 2 middle names (mackenzie) after my pop...

Congratulations.

My advice to you on the naming of your bundle of joy is that names can be spelled normally and still be unique...

Cohen Eli

Corren Eli

Marley Cohen

Cohen Ryel

... are all nice names spelled in their common form.

I only say these things for the trouble your child will have in later life with everyone spelling their name wrong.

I like Mackenzie, its more often used as a girl's name but i think it would suit a boy for a middle name, i tend to think family names are often better given as second names because there can be confusion, but in the case of relatives who have passed on, you can still show respect and love for your ancestors while also giving your child their own persona.

Cohen Eli Mackenzie sounds great (in my opinion)

Good luck, and congrats!
