Tobergloragh, in the townland of Ballynamanagh in County Galway, carries within it the Irish word tobar, meaning a well, most likely a holy well of the kind found scattered across the Irish landscape in their hundreds. These sites occupy a peculiar place in Irish religious and social history, functioning for centuries as places of localised devotion, pattern day gatherings, and reputed healing, often long predating the formal parish structures that eventually absorbed or ignored them.

Holy wells in Ireland frequently bear the names of obscure local saints or carry epithets that hint at their original character or the cures they were believed to offer. The second element of this name, gloragh, may derive from the Irish glórach, meaning noisy or babbling, possibly a reference to the sound of the spring itself, though such etymologies should be treated with caution. What can be said with more confidence is that the presence of a named well within a recorded archaeological monument suggests the site was considered significant enough to document, even if the details of its history, any associated patterns or patron saint, and its current physical condition remain unrecorded in publicly accessible form at this time.
