I have the book Przewodnik Po Zabytkach Gminy Tworog. This booklet was published in 2014 and has very nice photos and Polish explanations of the town of Tworog, which is very close to Toszek and Koszecin.
The ISBN number for this booklet is 978-83-64531-94-1.
The brown book on the left is another book about Tworog. It is entitled Gminy Tworog. The author is probably the community itself, gathering material from many members of the community. This book is subtitled Daqniej/Frueher/In the Past. The book is in three languages, so that I can also read this one. It contains mainly pictures of the community in past and gives a great perspective about life in the early years. It was very well done. I suspect there might still be some for purchase if this village is one of your ancestor's home places.I have an email address if this is of interest to you.
The author of this book is Fryderyk Zgodzaj. This book was published in the year 2013. The ISBN number of this book is 978-83-60071-62-5. There are also older pictures of Tworog in this book, however, it is written only in Polish.
And the last book is entitled Epizody toszeckie. The author is Jan F. Lewandowski and it was published in 2013. The ISBN number is 978-83-937265-0-9. On the cover, you can see the medieval pencil style drawing of Toszek. This picture was sent to me from my aunt many years ago when I first started doing research. I guess sometime in the 1970's. She had found a book somewhere about the history of Toszek. I so wish this one was in English as was the one Tworog book, but I am happy to add it to my collection of historical books of my ancestral villages. Thanks cousin Jan!
