I like
Hugh very much; unfortunately it's not practical where I live because many local people can't hear the difference between
Hugh and you. So that would leave me with
Hugo, which I also like though not as much.
Alma is the name of a road near where I grew up; it was named after the Battle of
Alma in the Crimean War, so it doesn't seem particularly human on two counts. Good meaning though, if you go back to the Latin as in
Alma Mater.
