“You may have asked, ‘Which is the best online genealogy service for me to use?’….I suspect this video [presentation by Sunny Morton at RootsTech 2017] will answer most of your questions. Topics covered include cost, record types, geographic coverage, genetic testing, DNA matching, search flexibility, languages supported, mobile-friendly, automated matching, and a lot more. Sunny provides the most information about these four sites that I have ever seen in any other one document or video. This is a keeper! I have been using all four of these web sites for years and yet I learned several new facts about them, thanks to Sunny’s online video presentation. I suspect you will learn some things as well.”  – Dick Eastman, Eastman’s Online Genealogy Newsletter
