No, no early night for you !
I have a nice cuppa handy and some Tim Tams !
So, 1903 Electoral Roll for North Sydney and polling place of Mosman's Bay .... NO sightings for Kenna .... (it was not compulsory to enrol)
So I am currently looking at 1903 NSW ER for Canobolas, and at East Orange page at this minute (weather report for this evening from a rellie who lives there .... could SNOW shortly)
KENNA at East Orange,
Back shortly to add their names here !
EDIT 1
John KENNA, William Street, Stock and Station Agent
Maria KENNA, William Street, at her domestic duties
I will keep looking (I also have NSW Country directories so I hope to find your Rupert's parents somewheres!)
