Welcome to the website of the Penfold one name study.

A one name study is a project researching all occurrences of a surname across the world, as opposed to following just the ancestors or descendants of one person or couple. This site is a repository for information about anyone bearing the name Penfold or variants of the name.

The surnames Penfold and Pinfold are registered with the 'Guild Of One Name Studies' which is the world's leading organisation for one-name studies.

The Guild is a charitable organisation dedicated to promoting the public understanding of one-name studies and the preservation and accessibility of the resultant information. Founded in 1979, the Guild now has over 2000 members spread across the world, studying over 7500 individual surnames.

Associated with this surname study is a Penfold Y-DNA project and an email list supported by Rootsweb.

The email list was launched on 26th September 2000 and the Y-DNA project on 15th March 2009.
