Hi Donald, Thanks for your message, however, I am no help to you as I am trying to find out my Devonshire connection too. Our William Perrim b. abt. 1830 all we know is Devonshire UK and that is all. It is very difficult to research from Sydney Australia.
If you do have further information of your relations other than the previous message eg. names, dates and states in australia then I might be able to go to the library and look up for you. Kind regards, Julie.
