I do not think that we should look much for the origin of an 'Aunt Cleta', since she is a wildcard character in the sayings, sometimes well used in the rhyme (as in "Aunt Cleta's dog, which the first time she barked she was broken by the jeta") and others not so much (as "Aunt Cleta's rooster : bald, but singer" or also "Aunt C's girl , who eats the petates and is frightened by the fans') . And Aunt Cleta not only has animals, there is also a tamal (like "Aunt Cleta's tamal, which was finished tested" ), and I think even an umbrella, . . . See being like Aunt Cleta's marrana.
