Hi Katharine,
With the help of a very talented Rootschat team and the purchase of certificates we have been able to go back a bit from where we were:
Felix McKanna, occ Butcher, married Catherine Ford, Ireland.
Son: John McKanna b.1809 Armagh, Northern Island, occ Farmer. d.1863 Maitland NSW Australia
married (1st ) Ellen of Helen Caffrey b.1822 County Galway, Ireland. d.1858, Ravensworth NSW Australia.
They had 5 children:
Thomas b.1844 Port Macquarie, married Mary Carney & lived in the Grafton area.
John b.1846 Port Macquarie, married Sarah McPherson.
Catherine b.1846/48 Port Macquarie, married Hugh McPherson.
Laurence b.1849 Maitland, married Mary Ann McLennan & also lived in the Grafton area.
Helen b.1851 Port Macquarie, married John McLennan.
John's ist wife Ellen/Helen died in 1858 so John re-married in 1859 to Mary Macquarie b. abt 1837 NSW
They then had 3 children:
Margaret b.1859 Port Macquarie.
Charles b.1862 Yarras, NSW, married Annie Ada Francesca Beissel b.1864 New Zealand.
Mary b.1864 d.1864 Port Macquarie.
Katharine, I haven't found any link with Bathurst area, they seemed to mainly around the mid north coast of NSW, although I don't know where John 1846 and Sarah went.
