Geoffrey Lynch (Mayor), aka Geffere Lynch, 4th Mayor of Galway, fl. 1488-1489.
Lynch was a member of one of The Tribes of Galway, and during his term of office he oversaw the introduction of the Dominican Order into Galway from Athenry. They were given a site overlooking The Claddagh, on the west bank of the river Corrib.
Lynch is said to have been knighted. He was married to a daughter of Walter Font and had at least one child, Anastasia Lynch. He may be the Geffere Lynch who was elected Mayor in 1500.
