Hi Dalmeny, You will no doubt know a lot more by now about Dominick.
My grandfather was Dominick Devir (jnr) twin brother of Michael (Mick), and my father was Mervyn, brother of Warren (& others). Warren's son, Wayne, has written a family history collating stories passed down about Dominick Snr's life and the family life at Bowraville, Scotts Head and Worrell Creek, with some photos. As a child, I used to visit Dominick Jnr & Dorothy at Worrell creek. I have only just found my copy gone on damaged hard drive- will have to get another.
Nobody appears yet to have found anything much about life and deaths of John Devir/Ellen Ferry or their parents.
Dom Snr's marriage to Julia in 1970 appears to have been a type of arranged marriage. His journey to Sydney, marriage in St Mary's Cathedral, then back in the horse & sulky to Bowraville for the honeymoon, and swimming some creeks, in a legendary story in the published social history of the Nambucca river. The Bowra wharf that handled all the river cargo was jokingly called Port Devir since built on his property.
A list of families in Donegal in 11th-16th century, lists O'Devir & no O'Divers. The Diver name may have been an English deviation. The Griffith's Valuation in 1857 for Clondahorky, lists Ellen Devir (& other Devirs) in Magherablad where Dominick snr came from. There were no Divers listed in Clondahorky in 1857. The Diver name on the Passenger records appears to be a mistake - ability to write problematic. Whilst his first 2 children (John & Joanah) were born as Diver in 1872, 74 - he had changed his name back to Devir by the time the twins were born in 1881, and Ellen in 1883.
I am helping to collate a history of the Bowraville Football club, which started playing Rugby Union in 1884. John Devir played for them in 1898, (1900?), 1901. Club folded 1902-1904. Dominick played 1905, 1906 (with Mick), 1907, 1908, 1909 (Mick Vice-President), 1910. No further detail yet. Source info bit patchy. My mother, (still alive with good memory and just had driving license renewed at 93), claims Mick played for Macksville in some years which created some friction. She has a 10 x 8 sepia photo of the Bowra team in 1907, plus two others likely 1905, 1908 with Dom in 2 of these. Cannot see a twin though. These will probably end up in the Bowraville Museum. Got no further yet. All Rugby Union folded during WWI, started again in 1919, and most North Coast changed to Rugby League in 1920. My brothers and I played League for Bowraville over the 1962-95 period.
If you have not seen a copy of Wayne's collation, I can forward a copy when I retrieve, if you make contact. The Rugby union history with photos will most likely end up on line somewhere, but I can send higher resolution copies of the original team photos if of interest. I also have a reasonable photo of Dom jnr in mid life.
