Name of the ship was possibly "The Grasstree" nothing definate yet though, the Eliz Markwell is correct, and Thomas was born in Louth in 1845, and Eliz M was his mother, but, Thomas was not his father, from what i can gather, Thomas was his Grandfather, his father being Joseph G, b???? married Elizabeth formally Aitken nee Markwell. Thomas G b1845 d1930 at Yuleba Queensland. I have a lot more on Robert Charles including his birth Certificate, Robert is/was my Grandfather.
