I'm one of 5 brothers. The others being David, Peter, Mark, and Robert. Our father is Harold Tidman and he has 2 brothers - George Tidman in Surrey and Donald Tidman in Norwich. We emigrated to Australia in 1967. The family have been optometrists/ophthalmic opticians for several generations and Grandpa Tidman lived in South Lambeth Road, Kensington. I will have to quiz my father for his first name. Our cousin is Roger Tidman (the bird photographer). If anyone out there knows something about my ancestors I'd be happy to hear from them.
