Do you think many Britons are unaware the island of Ireland exists?

I've noticed on tv quiz shows it rarely comes into their minds as a possible answer to a question. Name a place that begins Dub.... Dubai? Dubrovnik? It brings out the poet in me:
" Mystery island lost in mist
Even by the sun, rarely kissed;
No wonder some natives are sometimes pissed
Do include us on your list.
Land of enigmas and of mystery,
But whatever you do, don't mention history"
