AZ Pima Co. I checked with the Arizona Historical Society and there was no sheriff of Pima Co. named Thomas Drexel. However, there is a Drexel Avenue in Tucson close to my house and the Haydens lived in Tucson before going to Tempe. I take it you are not in the USA. If you are not, please contact me privately and I will see what I can do to help you further. Unfortunately, the state is not too keen on the net and doesn't give very good service there.
