A little more on this, speaking to my wife, she remembers the Davis family and confirms what you said about the diverse business, hairdressing, umbrellas and fishing tackle. She believes he had two daughters, small, darkhaired girls, who both attended Tamworth Girls High School, as did she, but they were older than she, (now 73) She believes one married a bookmaker, and lived in a bungalow or house in Salter's Lane, Tamworth. Does any of this tie in with what you know?
