Tracing your ancestors may be a fascinating hobby, but I don't see that Progen has much to add to it. Progen allows you to record the family relationships of up thirty people from five generations, using a tree diagram. Details of names, place of birth and so on are then entered on to "family group sheets" which can be printed out.
The big problem is that to expand the number of people covered you have to save lot of different files using different Root names. This makes the business so tedious that I can't help thinking you'd be better off with a WH Smiths notepad in the first place.
