From History.com...
New immigrants, especially the millions of Irish fleeing Ireland's potato famine of 1846, helped to popularize the celebration of Halloween nationally. Taking from Irish and English traditions, Americans began to dress up in costumes and go house to house asking for food or money, a practice that eventually became today's "trick-or-treat" tradition. Young women believed that, on Halloween, they could divine the name or appearance of their future husband by doing tricks with yarn, apple parings, or mirrors.
