overnight pancakes

A nice elderly woman made the best pancakes, maybe the best in world.And she grew up in Newtown in early 1900s.I recall them having yeast and setting on the table out in porch overnight.She wrote down many recipes but I cant find this one.Many children grew up in her home during the 30s, the depression put many kids on the "state " as people say.thats another blog, do you think they wanted that ?..OK pancakes, do we have anyone that knows about these pancakes?I am hoping someone has it written down.It would be at least 60 to 100 years old.
