There is one house on one of the Ozones - I think it's Little Six Mile. Another Ozone has a structure on it, but I don't think it's a house.
For the record, under anecdotes (not to be confused with antidotes), Birch Island (#2 on the list?) is connected by footbridge to Steamboat. In addition to the single home on Steamboat, that Birch has about 10 houses, but I don't have an exact count.
According to a photo on lakewinnipesaukke.net, Little Island has 1 house.

Could we be checking online deeds to find a count?
