A rugby player here in New Zealand has a son named
Tennyson and ever since I heard it in a news item about his family I really liked it. I don't think I would ever use it myself but I would love for someone else to use it.
Ten or Tenny are cute nicknames but are very 'pet' names if that makes sense, not nicknames that you would ever use to introduce yourself. I think
Tennyson on its own is lovely.

For some reason I think it suits middle names starting with a G or a J :)
