Records dating from 1853 to about 1870 in Victoria, Australia, have the same person (clearly identified by documents, the dates, the occasions) known as Dunphy or Dumphy. It could have been that the hearing of some clerks decided the spelling. These were literate people, although at one marriage the daughter of a school teacher signed with a cross, but then her school teacher nieces also occasionally suffered the same spelling confusion. I have often wondered what pressures were being exerted on these people that the correct spelling of the name was not recorded. Some Irish records were available to me years ago, in which the same Dunphy/Dumphy confusion was recorded. Rosemary
