I am interested in the Gall connection you mention. It appears that Magdalena Muller, daughter of August and Magdalena (Moos) Muller married into the Gall family. Also I find The Thurstenson name in a Boyd County History book probably published in the late 1930's or early 40's I'm assuming they are your family. Are you familiar with the book? Mine came from my mother and is missing the first four pages and ends at page 86. Thanks for your work on the early history of the citizens of Boyd County.
