Aww Archie is gorgeous! So excited for you hun

I like all your choices (I presume Che is pronounced like Che Guevara?)
I also played with the middle name George but DH decided he didn't want it (and its a family name) to my disappointment.

I think you have some lovely choices there.

A couple of other middle names for you

Harrison/Harry
Ben
Oliver
Luke

Best of luck!
