[1][2] Due to the loss of all records from Alpha Prime and Alpha Third was lax in record keeping and ended in scandal, there are gaps in information, especially from 1858 to 1875.
[1][2] In 1877, James Eaton constructed a multi-part history of the fraternity for the Crescent magazine from his memory as the founder of multiple chapters, from the fraternity's records, and interviews with living chapter founders.
[1] He documented chapters and name changes that were unknown to William Raimond Baird when he published the first edition of his Baird's Manual of American College Fraternities in 1879.
[3][1] Baird also lists charter dates, but leaves the institution's name blank in some instances.
[3][2] Eaton often fills in those blanks, but tends to list institutions by place name only which presents a different set of challenges.
