Hi Dustyrover, I am a direct descendant of Catherine Hackler (Maria Dorothea 'Catherine' Flegler). Like you I had exactly the same information from the NSW BDM (marriages) where she is named Hackler, until earlier this year when I visited the Cooma Historical Society. George Scott and Catherine Flegler are my GG grandparents. George S was born in Perthshire Scotland and Maria Dorothea 'Catherine' Flegler was born in Bettingen Germany. George and Catherine were married at the residence of William Stevens (just outside of Cooma), also my GG grandfather. Eventually a son of George and Catherine (James) married the daughter of William Stevens (Ellen) - I am a direct descendant of James and Ellen. Maria Dorothea 'Catherine' Flegler emigrated from Germany aboard the 'Catteaux Wattel' in 1855 as a child, her parents were Johann Georg Flegler born Bettingen Germany and her mother Anna Maria Diehm born Urphur Germany. Catherine Scott died at 2a Moore St Leichhardt and is buried at Rookwood; George Scott died at 21 Ilka St Leichhardt. I have heaps of information, would be interested in knowing how you fit into the family. Having a name Dustyrover, I gather you are Australian as I am.
