Hi Sue,
Yes the Forbes Henry & Mary are the right family, I received from a Transcription Agent Catherine ' Birth which was 5 Aug. 1867. info on it has got her father known as Henry Clague he was a miner he was 30 in 1867 birthplace Douglas, Isle Of Man, marriage 11th feb 1866, Currajong, Forbes Children 3 , 2 girls living 1 girl deceased (Illegitmate) Mother is Mary Barry age 25, birthplace Clare, Ireland
Informant Henry ( signed with X mark) Clague, Father, Bushmans Reef, Currajong.
I am pretty sure there were more children or Mary had a few out of wedlock! on Mary Death cert it says children of marriage are: Kate, William, Mary J, & 2 females deceased.
