Lindsey What you want sounds like Genome Mate Pro to me. I started using it about 6 weeks ago and the most complicated bit is importing the data and there are videos of how to do it and use it. Have a look at the screen shots on the web or the very helpful Genome Mate Pro facebook group were the lady who made the program is a member.

I'm used to the challenges of genealogy, but I don't want to be challenged by software. I don't suppose there is any simple program that allows one to place shared/identified segments on chromosomes. In other words, we have already identified a second cousin with whom my mother shares a number of large blocks so there is no doubt that all of them came from her maternal great grandmother. Likewise for the large blocks of shared by the fifth cousin once removed--also from her maternal great grandmother--and the fourth cousin once removed, from her paternal third great grandmother. > > Lindsey >
