[Ger-Poland-Volhynia] Thrun family

[Lloyd Friedrick]

I am searching for more information on my grandmother family line. 

Born   Bertha Charlotte THRUN,  18 March 1853, Frausdorf, Koslin.
Married  Konrad Hartmann FRIEDRICH,  6 April 1876, Alt – Alexandrowka Volhynia  Rozyszcze Parish
Died Lashburn, Saskatchewan, Canada, 08 May 1939

Father, simply known as Baron von Thrun born Stetten, Pomerania  abt 1830, died abt 1865
a landowner with Ruttergut, which was lost because he did not have a son as  an heir.
Mother, Louise maiden name unkonwn, born Stetten abt 1833, died Alt- Alexandrowka abt 1900
married Wilhem Hausschulz 29 Sept 1872, later marriage to unknown KARP.

There is a film index record of Gottfried THRUN as a landowner in West Prussia land records.
Thrun, Gotfr. Postlau am ( Kries ) Dirschau film  18011024  6035  244  45.

Hopefully, someone on our listserve can help me to find more records in the Stetten area.
