Cover beans with water and allow soaking overnight. Drain beans and combine with water in 2 litre sauce pan. Bring to a boil over high heat. Cover sauce pan with a lid and reduce heat; simmer for 2 hours. Drain beans, reserving 2 cups liquid (add additional water to equal 2 cups if needed) in a small skillet, sauté onion in butter until limp.
Preheat oven to 325 degrees f. in a lightly greased baking dish, combine beans, onions, reserved liquid, molasses, maple syrup, salt, mustard, and spices. Mix well, cover and bake for 2 hours, stirring occasionally, and adding boiling water if necessary.
Uncover and bake for 35 minutes or until brown.
