Hi Myluck!.
These three Murphy's travelled to Australia with my relatives, first stopping in Port Adelaide for a week, then travelling to Port Phillip together. Might help.
James McMurty and his family left their home in Carrickfergus in County Antrim and arrived in Australia as assisted immigrants on the barque Sultana, 588 tons, under Captain David Mainland, which sailed out of London on the 23rd March 1850. It stopped at Plymouth to allow the McMurtry family and other emigrants to board and left there on the 6th April 1850 with 251 passengers. It arrived at Port Adelaide, South Australia on the 25th July 1850. The ship took 47 days to reach the equator, and then made the run to Port Adelaide in 62 days.
The McMurty family, headed by James, a labourer from Antrim, went on to Melbourne with the Murphy family who were also on this voyage. The family was recorded as McMurty James (37), Margaret (36), John (16), James (14), Thomas (11) and Jenny (infant)
The trip to Melbourne was per the brigantine Elizabeth, 68 tons with Master Foyle towards Melbourne on Monday 5th August 1850. They thus spent 10 full days in Adelaide and arrived in Melbourne on Saturday August 10th as reported in The Argus on Monday August 12th on page 2
The Murphy family were all from Kilkenny and had 3 brothers and sister already in Melbourne. The traveller companions were John (32) a Labourer, Bridget (28) a Servant and Matthew (26) a Labourer.
