SharCotter on Family Tree Circles

Audrey Frances Innes was born in 1920 in Moruya Batemans bay area. She married Clem Kellehe on the 18th of April 1936 when she was just 15 years old. This was organised by her mother Alma.
She was then coupled with a man
named Edward Cotter, who was a station Hand at Roto??
He is the father of my father. Audreys husband Clem Kelleher died around 1960. She had 2 sons to him. Maxwell Kelleher and Kevin Kelleher and 1 daughter Margaret kelleher. She had Patrick Cotter, Michael Edward Cotter ( my father) and Kathleen or Katherine (kitty) Cotter all with Edward cotter between 1940 and 1960. I don't believe they married and I can't find where they lived together. Some family members have suggested Mt hope or Hilton assessable areas.
If you have any information, please let me know. My father is now in his 70s and has never really known much of his father's extended family. Other than possibly meeting one of his uncles when he was around 7 years old, who he thought was in the war. Any information will help.
