Hi Peter, My daughter has been doing the Family Tree bit through Ancestry.com and surprise, surprise discovered I have not one but six half brothers. Also that you and David are twins. Since then (January 2016) we have been in touch with David via Skype. He may have mentioned this to you. My Father was Bernard Lynch seems he was a busy boy! I visited the Martin Baker factory when I was in the UK, however he was deceased unfortunately. I am doing a tour of Vietnam Cambodia and Thailand in August this year expecting to be in Siem Reap 17 August 2016. Would love to catch up.if you around at that time. Cheers, Danielle Osborne Lightning Ridge NSW 2834 Australia.
