I have to admit that my research has been really unorganized in the beginning, but I guess I was overwhelmed by the available information. On the internet, I have found some research templates in the meantime for a better organization. However, none is fully practical for me. Therefore, I tried designing my own template.
You can download the template here as PDF. This template is intended for the collection of entries of an index of a church book when searching for a particular surname. The template also includes a detailed explanation on the last page.
While I so far took note of all the entries on a piece of paper which I could not find any more months later, I now intend to keep this filled-in template and if I am researching a certain name/book for more details or for relatives of the persons in my family tree at a later point in time, I do not have to undertake the entire seaching again.(Although it can also be quite useful to start again from scratch, as it is always possible that I did not notice some relevant information the first time).
Anyway, I hope you find the template useful as well!
