I am searching for an archives or repository where Officer records for the Royal Prussian Army may be kept.
Details: Major and Bataillons-Commandeur F. Zschetzschingck appears in the Thorn, Westprussia Adressbuch in 1876 and appears to have retired with a pension according to the Militär Wochenblatt of Apr. 12, 1877:
"Zschetzschingk, Major und Bats. Kommdr. im Riederschless. Fuss-Art-Reg. Nr. 5, als Oberst-Lt. mit Pension nebst Aussicht auf Anstellung im Civil-dienst und seiner bisher. Uniform,"
I believe that he first appears in the Rang und Quartier Liste in 1851 with the 4th Artillerie Brigade, Royal Prussian Army, as a Second Leutenant.
If Officer records exist, would they detail his career, genealogy data, postings, etc.?
