Meh to all these. Nice enough names, but no panache.

Marcas - Yeah, but spell it Marcus
Austin - Really like it.
Bartram - not really. Barton or Bertram I like better.
Carson - it's cool, but isn't there a famous female Carson somewhere?
Aleck - love it, but prefer Alec as a spelling
Merrick - as in Watts? Either way, I think it's a great choice.
Angus - I love this name. Love it. Could never use it myself though
