I am related to Margaret Jane Stoker and Samuel Maddock's son (Samuel McDonald Maddocks). They emigrated to Tasmania in August 1832 on the "Wellington" and had 8 children all up that I know of (Orlando Jeremiah born in Liverpool, England, 8 March 1832) and the following born in Australia, .... Sophia Louisa, Adelaide, Margaret Jane, Emily Amelia, Frederick George, & William Edward.
Samuel McDonald Maddocks married Martha Scarlett in Melbourne in 1875.One of their 5 children, was Margaret Jane McDonald (nee Maddocks) who was my great grandmother.
I can fill in some further info on the family if you wish.

Curious whether there is a link between Margaret Jane Stoker and "Bram Stoker" ??
