Planet Gilhooly is my mapping project for all of the Gilhooly family. If you'd like to add yourself and your family to the map, just fill in the form, and I'll add you as soon as I can. This is still a manual process (but an improvement over the "send me an email" from days past), so hopefully, eventually it will be more stream-lined.
The only requirement is that you have a Gilhooly somewhere in your ancestry. I'm just trying to track how our surname is moving around the world.
