Filling in the online tree at Ancestry.com

My family history research has been progressing slowly over the past month or so. I had been having a bit of a hiatus in my research efforts but the request for an introductory genealogy class at work has reignited my interest. I have been working on getting more of my tree on the web using the resources at Ancestry.com. It is duplicative work - I already have my extensive tree in Family Tree Maker, but duplicating that work allows me to connect more easily with other researchers.
