An interesting article from Carolyn L. Barkley. This helps explain about wikis for genealogy.
The purpose of the Pennington Research Association is to gather all Pennington cousins together, to provide as much genealogical assistance as possible and to work together to further Pennington research. Our goal is to collect, preserve, maintain, and disseminate material relating to the genealogical structure of the Pennington Family. The Pennington Research Association, Inc. is a not for profit corporation, incorporated in California in June, 2001.
