Looking for Robbie from Northern Ireland?

This is going to sound very vague and silly but i would like to find someone i met on holiday 6 years ago. All i can remeber is that he was small and ginger, called Robbie who was on holiday with his family and his friend Ciaron. We met in Menorca in S'algar and had a great laugh together for 2 weeks. I am so annoyed i cant remeber his last name but would love to know how he is. He will be about 19 years old now and his birthday is in February. Any good websites I can look on (have tried facebook, friends reunited etc but not much help seeing as i dont know much about him)
