Linkpendium is a genealogy index site. Although it is not as extensive as Cyndislist, it does boast over 7 million genealogy sites that are arranged by geographic location or surname. Its history shows that it is continuing to grow by several thousand additional links each month. This may be a good resource to use in addition to Google and Cyndislist as you search for your ancestors.
