Judith - As far as I know there is no list for south west slopes but others might know of one. I am replying to you because I am researching Wark family originating in Mudgee and esp Coonabarabran area of NSW. Samuel and Elizabeth arr Aus 1838 he from Co Donegal and she from Co Londonderry. Their eldest son John Cuthbert Wark m Mary Wesley and took up land near Coonabarabran in Belar Creek area. Another son William m Mary Jane Williams and lived in New England area of NSW. Are you connected do you think? I would love to hear from you and have lots of info to share.
