My husband's paternal line is Rubie, from Cork, Ireland. When his branch emigrated to UK in 1860's it became mis-spelled as Reuby, which is how it is spelled now. So you might try looking for Ruby, Rubey, Reuby if you haven't already.
Yeah, the middle names are interesting, Angela's birth doesn't give a middle name yet the marriage does, assuming the correct one. There are also 2/3 couples with similar names in Sydney and Molong with offspring at a simlar time.
