Hi Isk,
Not sure why you are researching the Dinnerville name, however, I am a great grandson to Lawrance Robert Dinnerville who immigrated to Oz from Scotland via St. Helena. My grandfather was Leonard Dinnerville the youngest son of Lawrence(Bob) and Sarah, whom I have an early photo. My father was Keith(Roy), the eldest son of Leonard(Len) and Emma(Cis). Lawrence and Sarah had four children, Lawrence, Charles, Beth, and Leonard(sometimes spelt Lennard). The three 'boys' all served and survived in the Great War.
I was told that the Family Bible, which came out with Lawrence in about 1873, is in the Archives of the Mitchell Library in Sydney and has various family name spellings as well as some 'blanks' for the name of some brides!
Lawrence and Sarah lived in both Strathfield and Homebush, suburbs of Sydney and Lawrence was one of the local Constabulary, and affectionate called 'Scotch Bob'.
Lawrence's brother, Robert, immigrated to the USA from Scotland in about 1870. There are many 'dinnerville' in the USA and I have meet a few cousins and an Uncle Robert who cruised into Sydney back in 1972 and introduced himself, and wife, to my father and filled-in some interesting details about the 'US Connection'.
As a note, I was told by my Grandmother (Cis) that the dinnerville name was originally the French name Den(n)eville, who were vignerons in Normady region and escaped the guillotine to Scotland in about 1790. The surname was said to be bastardised to escape the French who had spies out looking for those who fled France during the 'purge' by Louis XIV.
Dinnervilles in Scotland in 18th and 19th Century were also associated with Scotch Wiskey production, and a brother also had a laundry business in London.
In my research and being told by relatives, that names, both christian and surname was often mispelt because of either poor spelling or writting skills. I have seen this in many examples of records and letters.
Hope some of this helps your research.
Cheers, Keith B L Dinnerville
