Does anyone know what the words mean in the song?

Is the bold Riley a type of boat or is it a sailor? What is whitestocking time!!?? I know that I am middle aged as I now want to know the meaning behind folk songs!!


BOLD RILEY

Oh the rain it rains all the day long,
Bold Riley oh, Bold Riley
And the northern winds, they blow so strong.
Bold Riley-oh has gone away!

Chorus
Goodbye, me sweetheart
Goodbye, me dear-oh,
Bold Riley oh, Bold Riley
Goodbye my darlin
Goodbye, me dear-oh,
Bold Riley-oh has gone away!

Come on Mary don't look so glum
Bold Riley oh, Bold Riley
By Whitestocking day, you'll be drinking rum.
Bold Riley-oh has gone away!

Chorus


Our anchor's aweigh and our sails are set,
Bold Riley-oh, Bold Riley
And those Liverpool girls, we'll never forget,
Bold Riley-oh has gone away!


Chorus
