It has a certain charm, but it does have difficulties where I live. People who speak Afrikaans as a first language have a strange tendency to hear
Hugh as You - a colleague once asked me how I knew something or other, and when I said "
Hugh told me" (he was a senior colleague) she said in amazement "No I didn't!" There's a limit to the amount of bizarre I can willingly live with.
I also prefer
Hugo, in a straight fight. If I'd had a second son, I'd have used
Hugo Daniel or
Daniel Hugo (DH's family tradition is
Daniel + an H name).
