This is all a great help. I have a missing Robert b 1820 & another 1869 (both Ireland) as well as 1878, the one who married Robina. I suppose the age given could be a mistake & it could be Robert(1869) I think I shall have to get the certificate for that death & maybe the marriage cert as well to check witnesses now I have the references.
All this information has been wonderful, including her occupation.
By the way, if I can prevail further on your great good nature, I have a Patrick SHEEDY married a Mary SHARP in Tasmania in 1861. They also have simply vanished!
I am in New Zealand, no sign of them here. Though Robert & Peter did visit.
