Not far from Sneem (co. Kerry) there is a beach called Coral Beach. It is located nearby a quay called Gleesk Pier. According to logainm.ie the Irish name of this pier is Cé Ghlinsce. I've studied the sources mentioned on logainm.ie but I couldn't find the meaning of 'Ghlinsce'. Is it (the genitive of) a person's name? It is (the genitive of) another noun?

Thanks in advance.

"Glísg, 'is the local pronunciation, but it is decidedly a corruption of,' Gleann eisce, 'glen of the channel'"
(J. O’Donovan, 1838)

Decidedly?
There are a lot of places called Glinsce.

"Glinsce ‘valley’?
The etymology of glinsce is uncertain; it appears to be a derivative of glinn (gleann)."

This is what Tim Robinson says about Glinsce in his book "Connemara".
A brilliant book about natural history in South Connemara.


"Glinsce - from an old word glinn/secure, perhaps because the hill is a natural lookout point over the bay. "

Thank you both for you reactions.

If gleann eisce were correct, what kind of word is eisce in that case? A noun in the genitive, I presume. But belonging to which nominative?

Perhaps:
