Leave it with me, I will ask around for you. Should have an answer by lunchtime tomorrow at the very latest.
Well, that should be easy enough.
After all, there will only be one 63-year-old in the whole of Spain who has a wife called Jenny.....
Try putting your question on a Spanish site and just say you are looking for 63 year old ? & Jenny whoever and hope you get a reply or try facebook, Good Luck
The chamber of commerce in the city he might be can help you
What is HIS name?
Oh, wait...this is a TRAVEL forum. We don't do people searches. There are private detectives, websites, and phone books for that.
Helps if you know where he lives, too.
Why don't you try talking to your sibling/his parents?
he is 63 his wife is jenny
