I wonder if someone could tell me where to look for the records of Prussian Military Doctor's between 1790-1850 ?
I've been researching my 5 x ggrandfather for many years and yesterday received a letter from an archivist at Ringsleben in Thuringia which provided me with the details of my ancestors birth and baptism in 1814. The letter said that his father was thought to be a man called BERG, a doctor in the Prussian Army. I have access to Ancestry.com but with so few details I have no chance of finding 'BERG' there.
Where should I start as regards finding BERG's military service please ?
