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.
