Many thanks for your information, its very helpful. I work on the tree which we have on Geni when I have time. I've been using census and BDM data from Scotland's People and Family Search. My brother who lives in Darwin focuses on the Australian side as we were early convicts & settlers in New South Wales & Western Australia on my fathers side from Ireland, Scotland and England.
We are on Geni because my mothers father was Estonian and Geni is also in Estonian so we have matched with many relatives from there. Because of the language barrier I some years ago paid for a search by the Estonian biographical Centre which has proved very accurate.
Again thanks for your assistance
