I have found these useful: 1901 Census of England and Wales Online Welcome to the official 1911 Census website Unfortunately the trail on my Great Grandfather (Welsh Regiment 1915-1917) has gone cold. I have his medal card, but his detailed records were destroyed in WW2 with most others. In the 1911 census he is in South Wales working as a miner aged 23 (no parents appear in that census), but he was not there in 1901 aged 13, and there were 139 13 year olds with his name in the UK. I would need to find either his place of birth or his parents names in order to go further, does anyone know which documents may have that info? He received a medical discharge in 1917 (4 bullet wounds and he survived!), do medical discharge records exist separately as presumably there would be some entitlement to disability benefits? (He went back down the pit at some point after he recovered so I guess he would not have got a pension).
