The following information presents the DRAFT publication of this one-name study.


The Guild defines a One-Name Study as: "Research into the genealogy and family history of all persons with the same surname and its variants." A one-name study is a project researching all occurrences of a surname, as opposed to a particular pedigree or descendancy. In short it encompasses the research of a surname over the face of the earth throughout the known recorded history of time.


Clearly this is a daunting task, even for an uncommon family name, and while the Roddy or Ruddy surname is not as common as Jones and Smith, it is also not extremely rare. It is estimated that there are approximately 10,000-20,000 individuals with these surnames living today. A rough estimate of all individuals recorded in history with either of these two names is on the order of 50,000-100,000 people total.


This study will never be completely done, and will always be a work in progress, but it is the intension of the author to post results as they are achieved, modifying them as additional information is discovered, analyzed, and re-analyzed.
