Yes A, Kathy is correct, advice IF you are doing an upload start with about only 50 of your most sourced profiles. Make sure that they all have dates and places. Use the lowest branches of your tree. Otherwise you will regret it, as you will spend all your time matching and merging profiles with others who have already created that ancestor. Unlike other sites our goal is one profile for each person that lived. It's a true collaboration. Welcome ! There are tutorials and videos to help guide you !!
