This talk will offer an overview of research on the placenames of counties Meath and Westmeath over the past 100 years – from Fr Paul Walsh's pioneering work The Placenames of Westmeath (1915) to more recent developments. These include: the ongoing work of The Placenames Branch on the townland names of Co. Meath (available on Logainm.ie); two PhD theses on townland names in Co. Meath, and one on Co. Westmeath – all completed in the last five years; and the innovative and community-driven Meath Field Names Project.
