Google Books is another good source. You can find a lot of good information in the old books on Google Books. The site has both modern and ancient books on it, some of which are scanned and readable on the site. The ones that don’t usually have links to bookseller sites where you can possibly find them, or request antiquarian book dealers to look for them for you.
If you do a Google Books search using your family’s last name (or first and last name) and location, you can sometimes find a book with useful information in it. If you’re lucky, it will be scanned and readable online.
