Not sure if they are related but they could well be.
Martin Fanning died, age 72, on 7 Jan, 1910.
Johanna Fanning died 26 August 1913, aged 80 years.
Johanna had come out to Victoria on the Dirigo with 337 other single young women. The Dirigo arrived in Mar 1859. Johanna was 26.
There were other Butler young women aboard who may well have been related to Johanna: Jane 22, Mary 23, Mary Rose 17, Rose M 16. But Butler is not an uncommon surname .
Martin Fanning married Johanna Butler in Victoria in 1864. Her parents were John Butler & Margaret O’Donnell. I could not find any baptism records for Johanna in Ireland.
Martin and Johanna had at least three children: John 1868-1960, William 1867-1933, & Johanna. Johanna died in 1940. They farmed near Kyabram at a place called Taripta.
Martin’s parents were William Fanning & Margaret Grace from Co Tipperary in Ireland.
William Fanning of Loughmore married Margaret Grace of Moyne on 5 Feb, 1827. Witnessed by Thomas Kerin & James Grace. They lived in the townland of Castletown in the parish of Moyne, Co Tipperary north.
In The Tithe Applotment Books and Tithe Defaulters lists there is a James Fanning living in Moyntemple. This was in 1827 & 1828. Possibly the father of William or a brother.
In Griffiths Valuations for Castletown, printed in 1849, William was living on 42 acres in Castletown townland.
William and Margaret Fanning nee Grace are buried in Moyne Cemetery. William was a farmer and died 27 Jan 1874, age 78. His wife Margaret died 10 Dec 1883, aged 74. (her death date & age from the civil record).
They had the following children: Patrick 25 Dec 1827, Michael 20 Dec 1829, James 26 July 1832, Martin 12 Nov 1834, Thomas 19 Nov 1838, and Judy (Johanna) 29 Mar 1842. All these children were born in Moyne Parish.
Patrick Fanning married Mary Kennedy and they lived in Castletown and are in the 1901 census. They do not appear to have had any children. Mary died in 1928. She was a widow and left 700 ponds to Patrick Kennedy. Most likely her brother.
I haven’t been able to find any marriage or death records for James Fanning.
Thomas did not marry and Judy or Johanna died age 28, single.
Michael married Johanna Shanahan of Lisdonowley on the 15th Feb1885. He died on 10 Mar 1887, aged 47 (civil death record dates & age).
