The Surname Society
Launched in November 2014, is a website dedicated to researching surnames. It has been set up by The Surname Society, which is a not-for-profit group founded by a team of genealogists from around the world. It focuses on single surname studies, with a vision to connect like-minded people by providing facilities which enable members to share knowledge, data and good practice with others. The society allows members to register both worldwide and is entirely online. Maybe it is just the group you have been looking for. Worth looking up. You can follow their news at http://surname-society.org/category/news/ , read study stories or join in the forum discussion.
