It's absolutely amazing what's out there. I've been trying to find information on my granfather, who was a Captain with P&O and Holts before and during the war. All I knew was that he died when he was torpedoed off Durban in 1945.
So, I started digging and found that he actually died in 1941, that he joined P&O at the age of 15, was torpedoed 3 times in WW1 and twice in WW2. I've found pictures of his ships, and details of his voyages and two newspaper articles announcing his death. Neither named the ship, which was the RMS Nova Scotia. My late mum hadn't known any of that. I'm trying to find out about her now. When my Grandad died she joined the Fleet Air Arm (at 17) and became an Air Mechanic at RNAS Stretton. I've found on the internet a great photo of her sitting on the wing of a Sea Hurricane with thirteen other Wrens. I'll keep looking. You wouldn't believe what's there until you start looking.

Good luck with all your searches folks.
