Name my UNIT commander

Good morning chaps and chapesses, I'm currently running a poll, to see what you think of naming my commander for my UNIT:1891 force. I want him to reference the Brigadier of course, so I've decided he has to be a Commadore, which it the naval rank equivalent to Brigadier. He also should be a Lethbridge-Stewart, I reckon. I can't decide if he should be Alexander Cameron Lethbridge-Stewart or Archibald Frazer Lethbridge-Stewart.

Of course you may think neither of these names suits the (probably great-) uncle of Alistair Gordon Lethbridge-Stewart, or indeed you may have a much better idea for someone to lead my UNIT troops. In which case, please add any suggestions below, thanks.
