The first comment came in from someone who found not only the website, but the page of a DNA study participant's line that mentioned a different surname that married into his line. I haven't yet optimized that website for the Google search engine, but it appears even the deeper pages within it are getting catalogued and retrievable by searchers.
Anyone can subscribe to the comment thread -even without posting a comment - of any of the pages at the website that interest them.
For those on this list who are in the DNA study, you might at least want to go to your web page at the site, scroll to the comments feature, and click either "subscribe by e-mail" or "subscribe by RSS". You will then automatically get an e-mail if anyone posts a comment relating to your line.
