I am a member of the following six bodies that link with my family history research:
The Guild of One-name Studies was founded in 1979 as a home for everyone conducting a study of a single surname, or group of surnames.
I have been a member since 2000 and am a regular contributor to the Guild's Journal of One-name Studies. In addition to overseeing the Guild's internal wiki, I am also a member of the Marketing sub-committee and a former member of the DNA Advisory Panel.
I have organised three whole-day seminars for the Guild on DNA testing: in May 2004 in Oxford, in May 2007 in Nottingham, and most recently in February 2010 in Cheltenham.
In a few short years the International Society of Genetic Genealogy (ISOGG) has become one of most useful resources for family historians anywhere on the web. With approaching 10,000 members, its goal is to "educate about the use of genetics as a tool for genealogical research, and promote a supportive network for genetic genealogists", which it does in spades. The centrepiece of research on the website is the regularly updated Y-SNP tree which ISOGG maintains, a great example of how amateurs are able to advance specific areas of scientific knowldge a few steps ahead of the professionals and the tenured.
I am also a member of the Society of Genealogists and the Cornwall Family History Society.
The Pomeroy Family Association was founded in 1997 when its first international reunion was held at Berry Pomeroy, near Totnes, Devon.
I write a detailed Annual report for the PFA's 200-odd members which lists every tree in a surname reconstruction process combining genetic and documentary data.
I started the Association's Y-chromosome DNA project back in 2000 in a collaboration with Professor Bryan Sykes at Oxford University. With 51 men tested, at that time it was the largest DNA surname project in the world. Since then we've more than doubled that number and the DNA side of the project is almost complete.
The British Association for Local History unites knowledgeable enthusiasts and professionals in all the supporting disciplines such as archiving and teaching. I'm a firm believer in the crossover between family history and other history disciplines, and I gain a huge amount from materials published by the BALH as well as the easy access to academics across a huge range of specialisms.
