Peter and Jerry:
If you have deduced the Ancestral Haplotype for your surname projects I
invite you to share your results in my Surname Projects YSTR Mutation
Whenever possible, comparison of haplotypes in a surname project should
be made to the Ancestral Haplotype, instead of one participant
referenced to another. See this example in my surname project for a
deduced ancestral haplotype in a surname project.
