As a quick reply and not going into individuals I'd say all those who've put themselves at our protective front, with little chance of being recognized.

On a personal note my two grand-dads were pretty cool, my maternal "pop" was in the 8th army during WWII. Saw some things that changed him, drank a little and had the occasional flutter on the gg's on his return, but loved his family dearly and never missed a days work through petty illness. My paternal grand-dad was to young for WWI and too old for WWII, was a farmer all his life and a champion gardener - have some of his horticulture medals on his watch-chain I wear. Was pretty much a total Calvanist east coaster. I only remember him speaking once. Most of the visits he'd be sitting dressed, totally silent by the fire. Never speaking. One time as a tott I was playing with the fire as usuall and obviously annoying my Grandmother, she was moaning at me and my Grandad spoke!

My dad was also a pretty good chap, had his foibles, but served his country in Malasia, and taught me honour and an almost calvanistic work ethic. Brought me up to have an almost medievil sense of honour... which admitedly hasn't always been easy, whilst having a spiritual side which wasn't entrenched in a set faith. Pretty good man. Feel he taught me right and wrong.
Thanks
