Using this site
Bookmarks are entirely in your hands. You manage the ones you want to have in your list. They are recorded in TNG's bookmark list, not in your browser's bookmarks/favorites. They are available only on the computer/device and in the browser you are using when you mark them.
If you are a registered user, your bookmarks are stored in a table in the data base. This means that you can access them from anywhere, provided you are logged in.
Suggestion: identify key people in your branch (eg, the earliest ancestor, your grandparents, yourself, any histories, photos, etc). When you are at the appropriate page, click on "Bookmark" (top right of the page below the drop down menus). This will be added to your bookmarks, which you can list by going to the Find drop-down menu and selecting Bookmarks. A sample listing is at right.
Note that the Bookmark link does not appear on all pages - such as the Home page.
