There are many sources for local history, not all of them obvious.
1) Local archives.
2) The features, buildings and other aspects of the locality. Thus streets may indicate ancient field patterns, and locality, street, public house and other names of features may indicate some aspects of history.
3) Newspapers and magazines - local, national and specific to a particular subject. This can include both the text (including letters) and the adverts.
4) What is happening in neighbouring localities.
