... is the world's leading organisation for one-name studies. A one-name study is a project researching facts about a surname and all the people who have held it, as opposed to a particular pedigree (the ancestors of one person) or descendancy (the descendants of one person or couple).
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 in Britain, the Guild has members all over the world, and
is widely recognised as a centre of excellence in one-name studies.
The Guild brings together those with an interest in one-name studies
and other forms of surname study (such as DNA projects).
Many members register a surname so as to embark on a Guild-recognised
one-name study and coordinate world-wide activity in studying the surname.
Only one person may register a specific surname, but membership of the Guild is
open to all with an interest in surname studies,
and is not restricted to those who wish to register a name.
