Herb Korra spent many years researching the history of the Korra and Mahrdt families. In 1987 he published a book. The button below will open a PDF file of the book. I have removed the section showing family trees due to the number of living family members exhibited there. The trees page will display more historic sections of the tree. I can provide interested family members more current family tree information, but will not display this information on a public website.
