I hoping to clarify where exactly Friedrichsburg / Friedrichsbruch or perhaps a similar variant immediately close to Kokotzko Poland.
Per this document there were about 21 different variants of Friedrichsburg / Friedrichsbruch in Prussia.
I found in other records references and looking at some other individuals' trees that indicate Kokotzko, Culm, West Prussia as well which from the maps appears to be the same area of today's Poland almost on the Baltic Sea.
I see some people in their trees identify it on their map as the Fredricksburg near Brandenburg or Lower Saxony and list the country as Germany; which I do not believe aligns with the records themselves nor my particular chronology.
This record from the above links has helped narrow my search:
Town|Pr| Kreis (district)|Protestant Parish|Catholic Parish|Civil Records Office
and I have found via a couple sources that Culm is now Chelmno and there is a Kockcko in the immediate vicinity between Chelmno and Unislaw but no Friedrichsbruch.
My specific records for the individual I am researching specifically says born in Friedrichsburg on 15 JUN 1864 , then it says they were christened a month later on 18 JUL 1864 in "Kokotzko West Prussia". The women the individual eventually married her and all of her family are also listed as from Friedrichsburg, West Prussia. At least a couple of their children were also born there as well.
I know where Friedrichsburg in Lower Saxony in what is today Germany, but the christening in Kokoszkowy, Poland (almost 900 km via today's shortest route) or Kokoszka,Chojnice, Poland (700 km via today's shortest route) a month later with a new born infant seem unlikely. There is also a Friedrichsbruch in Brandenburg that is approximately 250 K from Kokoszka in Poland and almost 600 km from the place in today's Czech republic.
There is a similar query I found on the web "Where is Cokotzky / Kokotzcÿ?" that does not end with a definitive conclusion but did have the following text referenced
From Family Search
"Parish register of baptisms, for Scharnese, Westpreußen, Germany, now Czarze and surrounding area in Chełmno district, Bydgoszcz, Poland. Includes records of Kokotzko, Westpreußen, Germany, now Kokocko (Chełmno), Bydgoszcz, Poland. Text in Latin and German."
This does not explain the Friedrichsburg / Friedrichsbruch reference though found in other records as I cannot find the Friedrichsbruch in the Culm region of Poland.
I have also found a single vague reference on Wikipedia to Płosków in Złotów Co. Poland which is 70 km from Kokoszka, Poland and 110 km from Kokoszkowy, Poland, and 120 km from Chelmno and I do not believe is considered the Culm region.
"Płosków [ˈpwɔskuf] (German: Friedrichsbruch) is a village in the administrative district of Gmina Złotów, within Złotów County, Greater Poland Voivodeship, in west-central Poland.1"
I mapped some variants of Friedrichsberg (red) and variants / references of Kokotzko (yellow) and none seem to really align to Clum/Klum/Chelmno (green) and none are immediately close to the known location.
I understand its location might be in a Map Guide to German Parish Registers Vol. 45 – West Prussia II but I do not have access to it via the local library or inter-library loan to investigate.
So the root of my question is where exactly is/was the Friedrichsbruch, Culm, Kokotzko in West Prussia?
