My grandfather's grandparents & father immigrated to Melbourne in 1871 from Nevers France to escape the Franco-Prussian war. They settled in Rutherglen, northern Victoria, and my grandfather, Lance, was born in 1909 there. The area was later named Dugay's Bridge. Lance's father's name was Theodore and he was born in Nevers France in 1857. His parents were Henri (born 1929) and Lucie Delagreviere (born 1841), also from Nevers. If anyone has any information on this Dugay line, please contact me.
