It is unlikely that 300 monks and 2,000 students were in residence at any one time at St. Féichín's original monastic foundation. The early "Lives..." often make such statements exaggerating the importance of the saint due to the political concerns of the foundations that commissioned the text.

The saint's name is also spelled "Féchín." Some sources say St. Féichín’s death was in 665. Most sources give his feast day as January 20, the day of his death, but some sources say he is celebrated in Ireland on the 14th of February.
His name may mean "little raven." "His name is explained in this manner in a note added to the Félire Óengusso, which says that he received this name when his mother saw him gnawing on a bone and exclaimed 'my little raven!'" (http://en.wikipedia.org/wiki/Féch%C3%ADn_of_Fore)
The "Yellow Plague" In England was known as Pestis Flava, and in Ireland as Buide Connaill. It coincided with an eclipse of the sun. Some suggested it may have been smallpox.
