I have the following information.George Kellner married Jane Mikkelson 1888 Clarence Town, NSW. (Is this correct?)
I have children Margaret b.1889, George b.1891, Mary b.1893, Roy b. 1895, Ivy Marie b. 1897, Alma b. 1899 and Veronica b. 1903. All children born in the Dungog NSW area. My g/aunt has informed me that there were 14 children in all, but I do not have any other names at this stage.She also informed me that one child, Elsie, is still alive and in NSW.Also that another child, May has a daughter living in Darwin, NT.My g/aunt will be forwarding more information at a later date, which I am quite willing to share with you.
