I was able to receive a recently published book by Jan Myrcik who is the proprietor of a local history museum in Koszecin where a large amount of my ancestors are from. In this book, the topics of war casualties and fatalities from Koszecin are covered. It includes the names of many of the participants of various wars, WWI, WWII, and some others in which villagers from Koszecin took part.
I was able to find many of my relatives listed in this book of 108 pages. The book also includes many letters from the military informing villagers of the loss of the relatives, sons, fathers and so forth who were determined missing and those that had been killed in battle. The book is written in the Polish language and includes the above mentioned letters, many of which were in the German language. It included photos of some of those that were killed or missing. For the Koschentin/Koszecin researcher this book is of great interest.
