The three dimensions in genealogy are Name, Time, and Place. You should be able to pinpoint records for a particular person knowing these three “coordinates.” As you twist the dimensions in different ways, new or previously unseen patterns emerge in your family history. This free online course titled, Rubik's Cube Genealogy: A New Twist on Your Old Data currently offered to the public offers some new insights into your old information. The course is 45 minutes in length and is presented in English.
