According to BDM Victoria, Patrick was the second of two children born to his parents Mary (Carey or Keary) and Richard Lane. His older sister, Elenor, was born and died in Melbourne in 1850. Richard's parents had married in Victoria in 1849.

Further information, from https://discoverytrailscomau.wordpress.com:

"Paddy was also of Irish stock, his father Richard Lane having migrated from Limerick to Melbourne in 1849. Richard had married Mary Carey soon after arriving and Paddy was born on 30th, September 1851. Unfortunately his mother Mary died in 1852 and his father Richard was shot by a madman at his property in Eltham on 30th January 1861...This left Paddy an orphan living with his stepmother (his father's second wife, Anne Hayes) and her sons and daughter.

Paddy's aunt Anne, who lived up the coast towards NSW with other members of Richard's wider family, heard that he was being treated unfairly and cruelly so she donned drovers' breeches, coat, and hat and rode alone to Melbourne. As he came out of school she stole him and took him back to rear him with his family and cousins. At 21 years of age he returned to Melbourne and went to court to claim his inheritance, the bakehouse, flour mill and food store that his father had run in Melbourne town. It was at this time that he met Bridget Carrucan and they married."

There is more, from home.alphalink.com.au/~datatree:

"Richard Lane b 1819/20, Shanagolden County Limerick, occupation farm labourer. Arrived in Victoria on board Runnymede on 30 Aug 1841. Married Mary Carey b 1816 on 24 Jan 1849 in St Francis's Church, Melbourne. Daughter Eleanor born 22 Jan 1850 but died soon after, son Patrick Richard Lane born 30 Sept 1851 and died Kalgoorlie 10 Feb 1926. Mary died 1852, Merri Creek. Richard remarried Anne Hayes, daughter of Michael and Margaret Hayes, originally from Tipperary. Richard cleared his 99 acres, purchased 1852, on the banks of the Yarra in Eltham and farmed potatoes until murdered on 30 Jan 1861 by his casual workman, (committed lunatic) James Montgomery, who'd lived in a bark hut beside the Yarra property."

A death certificate for Richard is not on record at BDM Victoria however newspaper articles confirm that a man of unsound mind named James Montgomery admitted to shooting Richard through the chest with a pistol at a coroner's enquiry and a jury found him guilty too. James turned himself into police at Eltham police station after he had killed Richard. Richard's grave has not been located.

Regarding Patrick's mother Mary, two women by the name of Mary Lane died in Victoria in 1852. One was 50 years of age and the other 36. The 36 year old Mary (Connell) Lane died at Merri Creek and was buried on 18/3/1852, and her husband's occupation on her death certificate was listed as labourer. She is on find a grave at Fawkner memorial cemetery, but with another spouse, a Timothy Lane she married in Melbourne in 1841, not Richard Lane. She is buried with Timothy and five other mainly Lane family members (Allen, David, David and William Lane and a John Dunne), so this doesn't seem to be her, although information noted above says otherwise.

The 50 year old Mary died in Melbourne and was buried on 17/2/1852 but we don't know where she lived (can't read the writing) and we don't know where she is buried either. But maybe she is the Mary we are looking for.

Also, a summary of a book called 'Escape to Eltham' by Georgina Allen "traces the family of John and Anna Lane who lived in Shanagolden in County Limerick during the early and middle parts of the 1800s. They lived during a time of conflict and famine. This story follows the movements of their son, Richard, and daughter, Anne, who migrated to Australia. The marriage of Anne to Tobias Butler and Richard's life establishing his farm on the Yarra River in the 1850s are explored. Marriage, children, deaths and a murder in 1861 are changes forced on the family. Richard's son, Patrick, marries a young Bridget Carrucan but when the global recession of the 1890s decimates Patrick's businesses he heads to the arid Western Australian goldfields to 'make his fortune'. The large family follows and settles in Boulder..." (www.lulu.com)

Regarding Patrick's Aunt Anne, her husband as said to be Tobias Butler above, was born 1828 Kilkenny and died 1871 aged 43 in Melbourne, grave not located. Details for Anne's marriage, children, death and cemetery location have not been located yet either. A Tobias Butler did marry in Melbourne in 1854, but to Ellen Brennan, not Anne Lane.

Richard is buried with his wife and two of his daughters who died young as a result of bubonic plague outbreaks in Kalgoorlie. In total, four of his 12 children predeceased him.
