Grandad

I have two Christian names, John and Edwin, named after my two grandfathers. I know almost nothing about Edwin , he died when my father was only five. This is grandfather John, a grand old man and father of seven, all of whom, except for the one killed at Ypres, lived to a ripe old age.
The origin of my blipname, Tedwin is obvious, but the reason that I chose it has already been told  on blip about two years ago https://www.blipfoto.com/entry/2318408903735378495 when Blip Central ran a similar challenge.
