How to Start a Search for Ancestors at Ancestry.com

My husband asked me recently "What's the first thing you do when you start to research a family?" I told him I start a new file on RootsMagic, enter the information I've been given by the person requesting my research, then I start my search at Ancestry.com. On their YouTube channel, Ancestry.com offers 100 videos with instruction for genealogy research. At this link, you'll find a 20 minute video by "Ancestry Anne" explaining how to start and conduct complete research at Ancestry.com. http://youtu.be/DIje7zcZLVQ
