Hi All >From various pieces of paper proof I believe that Roy and Robert F Haydon are the same person. Could SKS living in the State tell me under which circumstances someone would have had to provide proof of birth, or something similar early in this century. Roy rode with the Rough Riders and is listed as being born in London, England. However there is no such person on the 1881 UK census. Robert was born in India. Neither are on the SSDI, but Roys ???wife is. He is listed as being in the Prescott muster, but might have ranched in Florence, Pinal County. This is my first foray into US research and I am unaware of which records are available. Eg is there a census in 1900, 1910 or 1920 for Arizona. He might have died around 1920. With thanks for any assistance. Beth in Toronto
