Hello all. Looking for some information for a song:

What do we know about the typical life and work of a lighthouse keeper in the old days - let's say late 1800's - in the Canadian Maritimes (if different from elsewhere).

What were his responsibilities? I assume that the light was a fire that would be out during the day and that he would light at each sundown. Did he have to stay up all night to tend the fire? Did he sleep during the day, or chop firewood, or typically have some other job? Would he have sleeping quarters in the lighthouse, or a nearby house? And how did he get his food?

Thanks for any available help, Marion
