One of the recent marriages from film at the library:
St Silas Waterloo Sydney No 90
William Simon Cooper Bachelor Ottawa, Canada Engineer 24 McDonald Town John Cooper Eliza Leale ? Blacksmith
Charlotte Louisa Vowles Spinster Surry Hills - 30 Woolahra Isaac Vowles Jane...
Arrived in Australia 1901 - 1911 ???
Can any of them be found in 1911? Possibly the whole family came to Australia and not just Douglas and Hector McD. I don't know if that is McDonald or McDonnel or if it is his mother's maiden name.
