Just came across your post of December 10 2003, recognised the family connection and am responding.
I am a descendant of Thomas MARCUS/MARQUIS and Jane McALONAN/McELHONE.
My line of descent is through their son David MARCUS and Agnes(Nancy) BEGGS - David and Nancy are my great grand parents. They had eleven (11) children [William, Thomas, Samuel, Henry, David, Agnes, James, John, Margaret(Maggie),Joseph and Jane].
Agnes, my grandmother, married Henry McDOWELL; they had three (3) children [David, William and Elizabeth].
William, my father married Maggie McILWAINE; they had Four (4) children [Agnes (Nancy),Henry (Harry), Marcus and Mavis (that's me)].Our family came to Australia from Larne, Co. Antrim, N.Ireland in 1951 and settled in Geelong, Victoria.
My father had a cousin Elizabeth (Lizzie) MARCUS who married James MONTGOMERY and they had several children. They came to Australia (NSW) about 1929/30.We had no contact with them.
My greatgrand uncles (my grandmother's uncles) Henry and Samuel MARCUS/MARQUIS and wives arrived in Geelong about ninety-five (95) years before we did BUT I only found this out about twelve (12)months ago.Life is full of surprises isn't it!
Samuel and Mary had eleven (11) children, seven (7) boys and four (4) girls.Henry and Elizabeth had six (6) children, five (5) girls and one (1) boy.I have been in touch with a descendant of each of these brothers in the last twelve months and could provide you with details if you are interested.
I have no details of the fourth son of Thomas and Jane (James) and don't know if they had any daughters.
This seem a heap of information and I'm not sure if this is the sort of thing you are looking for or if you fit in with any of this.
