*edit* Thank you to everyone who commented. Unfortunately it was not the outcome we had wanted and have been informed that a gentleman we believe to be our dad has passed away. Thank you all so much for your help.
Hi its a long shot but after some investigation we believe our dad moved to Benidorm some years ago. Unfortunately for myself my mum. Wasn't a fan of me seeing my dad so I haven't since I was 8. If anyone has any information relating to a Brian Brooke (maybe going by Chapman) he would be about 65 and seven for many years in the Cheshire regiment. My brother and I would love to find him and hopefully reunite. Thank you for your time
