My suggestion for adding profiles is to prepare/plan in advance. This will be my first Thon. I decided to focus on a particular area and I have made a list of all the people who appear on the census lists in that area, and identified the various families. In advance of the Thon I have created one profile for each family, so that once we kick off tomorrow, all the other people in the family will count as connections to the first person already created. I have 150+ on my list and hope to get through them, as I know my primary source and can find them all quickly, but I will spend a few minutes on each profile and try to add birth/death records if I can, and then the "Needs Biography" category.
