I am trying to figure out how to cite the elements in a table for a series of men to indicate their ages and approximate birth years as taken from their listing in the 1850 and 1860 U.S. census records (as a substitute for lack of birth records for that time). In addition to the man's name, I want to list his location in each census, and his age in each census. The table includes about 15+ men. How do I provide a citation to each of the two census years for each man within the table? If I do a full citation for each, the citations will take as much if not more space than the table. Is it acceptable to use a shortened citation form and if so, what format? Or is there a better way to organize the data? I want to show the 15+ males in a related extended family who would have been of an age to have served in the Civil War, using their appearances in the 1850 and 1860 U.S. census records as the reference point for their approximate ages.
