100 Most-Visited Genealogy Websites
Recently the GenealogyInTime Magazine Newsletter released their list of the 100 top genealogy Websites of 2014. There may be other similar lists from other sources, but this one is based on Alexa results, so I believe this is the most accurate.
I like the fact that they provide a useful analysis of the types of sites and changes in ranking since the previous year. This is a free newsletter. I encourage you to subscribe. If you find you don't like it, you can easily unsubscribe. Besides good articles, they also have a genealogy search engine similar to Mocavo, except theirs is free. The magazine's home page is http://www.genealogyintime.com
The Top 100 listing is at:
Somewhere in that list may be exactly what you have been looking for. FamilySearch.org and FindAGrave.com continue to be the most popular free sites, but there are others waiting to be checked out.
