THE ABBOTT FAMILY TREE - AUSTRALIA, NEW ZEALAND, ENGLAND

I am researching the family of William ABBOTT (1855- 1912) from Blewbury, Towersey, EastHagbourne Berkshire/Oxfordshire UK who migrated to New Zealand approx 1878 and of his wife Annie McGUINNESS born around 1862 from County Clare Ireland. Their eldest son William George, his wife Ella Fallwell and their family moved to Australia in the 1920's approx.
I am also trying to find details of Catherine Cheatley from Co. Derry who married Ernest Louis Robert (from New Zealand) whose parents were believed to be French by birth. They lived in Gordonvale,Cairns and Charters Towers, Nth Queensland,Australia in the 1890's approximately.
I would be glad to hear of any information or ties to any of these ancestors and am willing to share information I have already obtained.
