The character's name allegedly came from using the Bristol Almanac, a long-standing almanac popular to Latin America that is published by New York City soap maker Murray and Kemp, and is similar in concept to Poor Richard's Almanac, as a source of baby names. The Almanac lists the Catholic saints of each day, from which a name could be selected for a newborn depending on the day of his birth; in theory this puts Don Eleuterio's birthday as occurring on 20 February, the day of St. Eleutherius of Constantinople, and right after the consecutive (and purely coincidental) birthdays (17 February - 19 February) of three Puerto Rican governors: Luis A. Ferré, Luis Muñoz Marín and Roberto Sánchez Vilella (in that order). Eleuterio hates his name, since it is decidedly non-American. In reality, Logroño used "Eleuterio" as a name to reinforce the character's Puerto Ricanness, since the coquí, a frog native to Puerto Rico, has the scientific name of "Eleutherodactylus coqui". Since the coquí has traditionally (and erroneously) been viewed as so local to Puerto Rico as to die if taken out of his habitat (proven wrong by its recent acclimatization to Hawaii), the name "Eleuterio" evokes a similar connotation.
