Abstract: An apparatus for constructing the genealogies of famous and/or noble individuals is disclosed. The device consists of a board or pedigree surface and a series of 63 prism-like structures--one for the subject and one for each of his (her) 62 ancestors over the preceding five generations.Each of these prism-like structures contains nominal information on a particular individual as well as a short biographical sketch or anecdote. Included in the sketch or anecdote is that individual's relationship to one or more members of the family tree. These familial relationships enable users to correctly place ancestors with the aid of certain known points within the pedigree.These known points are board positions which are labeled with the same nominal information as found on the prism-like structures. The great majority of board positions, however, are unlabeled and the proper ancestor for each of these sites must be deduced from familial relationships contained in the biographical sketches.
