curious as to what these are

These items were found while preparing for an estate sale. None of the family had seen them before or knew what they were. Because they were stored in a bedroom dresser with other collectables we decided to try and identify them. They apprear to be made out of marble, some of the round ones have some reddish stain, there are three "crowned" with flat bottoms and graduating sizes on the stones in back? Is this a game of some sort? Part of the family was of Norwegian descent, part Scot/English.
