Are you sure Oscar stayed in wexford County.There use to be a 5 and dime store in the Town of Bellaire,Antrim county with the name of Dahlquist Variety Store. It was owned by two Dahlquist sisters. There is a lake nearby called clam lake I am not sure if there is a clam lake twp. The store closed about 10 years ago, but had been there as long as I can remember and we have been going up there each summer since the 60's Perhaps this is your relatives. Bellaire is the County seat for Antrim County and is a big resort town. Shanty Creek Ski Lodge is there, perhaps you have heard of it since you only live in Livonia, If I can be of any further help feel free to email me at email@example.com.
