Thank you for trying to help, much appreciated.
I have a marriage certificate for Christian August Heinrich Hager (known as Henry) to Louisa Horn on 1 Nov 1856 in Germantown, Geelong, Victoria, Australia. His birth place is given as Flethe, Germany and her birth place is Pommerzig, Germany. He gave his age as 27, therefore born c1829 and he died in 1896 with an age given as 67 therefore born c1829
Family details initially gleaned from a book "Killaloo to Yan Yan Gurt" 1998 by Mac McCombe, (at State Library of Victoria, Australia) a descendant of Christian and Louisa, but no references noted in the book, but lately I found baptisms/marriages on Ancestry for those in Denmark
