Is it Eliza RENWICK 38, who arrived on the Marco Polo with James RENWICK, 36, ag lab, and Jane 9, and William 3, RENWICK? Their native place is listed as Antrim. The disposal list says that they went with Mr Chan, Geelong.
Arrival date: 20 Sep 1852, Hobsons Bay Victoria, Australia
Departure Port: Liverpool
Someone on Ancestry has suggested that the surname should be RENNICK, but it looks like RENWICK to me although the ink is a bit blurry.
