William Hugh Ferrar

William Hugh Ferrar (1826–1871), a Latinist, was a classical Irish scholar at Dublin University.
In 1868, Ferrar discovered that four medieval manuscripts. Namely minuscules 13, 69, 124, and 346, were closely related texts. They are descendants of an archetype from Calabria in southern Italy or Sicily. Now they are known as "Ferrar Group" or "Family 13".
