I'm not the only one writing about Geneaholism and recovery...
I don't know why it took me so long to discover ... GENanon, a blog by Thomas Hamburger Jnr who describes his blog as:
"We are a not-for-profit group that exists to provide succour and support to anyone, anywhere, anytime who has become addicted to the pursuit of their family history. "
He, of course, demonstrates his proclivities by writing a serial genealogy story at http://harrymcfryinvestigates.blogspot.com/ - where Harry McFry is the intrepid hero. There are 130 chapters so far - I'm not sure that is enough for a true Geneaholic. We'll see!
