The Nettelfield Family Tree

Hello everyoneI have just began researching into the history of the Nettelfield family and would appreciate any help you can give.I have so far found people of my surname in England (where I live), Australia, Canada and America. I am assuming that we may all be related somehow and am keen to find out how.I hope to contact all Nettelfields in due course once I have reached the limit of my research but for now please help !ThanksIan
