However if this story was true, José Marco would have had to explain why he didn't use this wealth of information or even mention these documents when he wrote his Reseña Historica in 1912. Perhaps Marco saw the flaw in his story so, when he explained the origin of the manuscripts to the Philippine Studies Program at the University of Chicago in 1954, he said that he had got them from an old cook who once worked at the convent in Himamaylan where Pavón had lived.
Subalit kung totoo ang kuwentong iyon, dapat ay ipinaliwanag ni José Marco kung bakit hindi niya ginamit itong kayamanan ng kaalaman o kung bakit hindi man lang niya binanggit ang mga kasulatang iyon noong sinulat niya ang kaniyang Reseña Historica noong 1912. Marahil ay nakita ni Marco ang kamalian sa kaniyang kuwento kaya noong ipinaliwanag niya ang pinanggalingan ng mga kasulatan sa Philippine Studies Program ng University of Chicago noong 1954, sinabi niyang nakuha niya iyon mula sa isang matandang tagaluto na dati'y nagtrabaho sa kumbento sa Himamaylan na tinirahan ni Pavón.
