Corn dolls have nothing to do with corn.
I've read from several sources now which contradict that. A lot of them relate to the Native Americans in their fashioning of dolls from the husks of corn...and calling them corn dolls. However, since Maiden is British, I'll throw out this, pulled from Wikipedia (admittedly not the asbolute best source for truth at all times)...
James George Frazer discusses the Corn-mother and the Corn-maiden in Northern Europe, and the harvest rituals that were being practised at the beginning of the 20th century:

"In the neighbourhood of Danzig the person who cuts the last ears of corn makes them into a doll, which is called the Corn-mother or the Old Woman and is brought home on the last waggon. In some parts of Holstein the last sheaf is dressed in women's clothes and called the Corn-mother. It is carried home on the last waggon, and then thoroughly drenched with water. The drenching with water is doubtless a rain-charm. In the district of Bruck in Styria the last sheaf, called the Corn-mother, is made up into the shape of a woman by the oldest married woman in the village, of an age from 50 to 55 years. The finest ears are plucked out of it and made into a wreath, which, twined with flowers, is carried on her head by the prettiest girl of the village to the farmer or squire, while the Corn-mother is laid down in the barn to keep off the mice. In other villages of the same district the Corn-mother, at the close of harvest, is carried by two lads at the top of a pole. They march behind the girl who wears the wreath to the squire's house, and while he receives the wreath and hangs it up in the hall, the Corn-mother is placed on the top of a pile of wood, where she is the centre of the harvest supper and dance."
—The Golden Bough, chapter 45
I think, based on what I've read, some believed that the spirit of the corn resided in the corn fields, and the harvesting of the corn left is homeless. I read further that they created a corn doll from thehusk of the last of the corn to be harvested, and the spirit of the corn resided there, until the next year and the seeds of the next crop of corn were sown. I think Maiden may have used that as imagery for the souls of the dead coming to a certain place, and then being reborn again....all the the while the story also paralelling along with the story of the Isle Of Avalon being the place where the souls of the dead are reborn.
I am VERY open to being told I'm wrong....but from what I've read thus far, this seems like a good working theory.
