Looking for poem

I only know basiclly how it goes but I've been searching for 2 Months.

Its about a woman who loved a sailor and upon his return as she waited on the cliffs he would always blink the flood lights 3x. On his last trip she waited and waited with no word and no lights. She is said to have died waiting for his return on that same cliff. And it is said you can still see her from time to time.

I dont know how accurate this is but please help if you know the name, Thanks soooo much

Srry idk
