Patrick ROBBINS was born in Co Galway, Ireland around 1835, the son of Patrick ROBBINS (farmer) and Margaret LYONS (Australian marriage certificate #3984). His death certificate (#11622, 12 Jul 1899, 64yo) confirms his parents' names and his year of birth and indicates that he spent 44 years in Victoria (arriving 1855). It also notes his father's occupation as 'bootmaker'.

An entry on a Galway emigrants list describes a Patrick ROBINS departing for Sydney on the ship "David McIver" in 1854, his age 21 years and native place Loughrea. It names his parents Patrick (deceased) and Margaret living at Loughrea and states that his sister Bridget of Pitt St Sydney paid for his fare (see http://freepages.genealogy.rootsweb.com/~maddenps/GALWAYEM.htm). The Shipping Gazette and Sydney general trade list (from http://www.nla.gov.au/ferg/issn/14403897.html) confirms that the "David McIver" departed Liverpool on 7 Sep 1854 and arrived 18 Dec 1854. If his age as described on his marriage and death certificates is to be believed, he would have been 19 and not 21 on arrival, though for whatever reason he may have lied about his age to make the journey. 

His sister Bridget came to Australia several years before per "Thomas Arbuthnot" which sailed from Plymouth 28 Oct 1849 arriving at Sydney 3 Feb 1850. Although her native place was given as Clare, she is listed as RC, of Loughrea, parents Patrick and Margaret and her reported age was 17 years which would make her Patrick's elder sister born ~1833 (from http://www.irishfamine.org/Diadem.html now defunct). It also records other details, a possible sponsor/employer "J. Oakman, parramatta St., Sydney , £8, 1yr". It says mother living at Loughrea, but doesn't mention the father (probably deceased).

There is also a James Robbins in the Victorian Index (Vic BDM #3102) who died in 1865, 26yo (b~1839) Galway, parents named as Patrick and Margaret – I’m presuming this is Patrick’s brother although I’ve not yet ordered the certificate to prove it. I haven’t been able to find him on a passenger list as yet so I’m not sure whether he came before 1855.

Patrick's mother Margaret (LYONS) died 1 Apr 1870 in Annabride (Annaghbride), a small townland about 3 miles east of Loughrea in Co Galway (there are about 7 houses there). The entry in the civil registration records reads:

1870 deaths registered in the district of Bullaun in the Union of Loughrea in the county of Galway
  (Townland = Annaghbride, Electoral division = Kilmeen, Registration district = Bullaun)

On 16 Nov 1869 (VicBDM #3984) Patrick married Annie MEHEGAN of Co Dublin (parents Denis MEAGHAN and Ellen YOUNG) and they had 6 children. They settled in Williamstown and were living in Pasco St when Patrick died in 1899.
