I had a look at the Times, but the closest I could see was a Henry Foster, 18, of Bow, died in 1928, after going to bathe in the Thames near Walton Bridge, having been visiting friends at Upper Halliford. He got beyond his depth and disappeared, and all attempts at rescue failed, the body being recovered some hours later by the police.
