Thank you for the links, Sam. I probably can't use methods that involve uploading their raw data somewhere else. Even though I paid for their testing, I think it would be over-stepping for me upload their data off site, and I'm uncomfortable even asking. These are not people I know well. All three had responded to my pleas on the web for cousins to test. So, Dr. Pike's utilities would appear to be the way to go. Thank you for bringing them to my attention.
