What a shock to see this item. I have a copy of the birth certificates of Anna and Amanda Hake - their father was Olaf Hake their mother was Elizabeth Erickson. the siblings were Ida, Magritta, Arvid, Nicholas, Edhar and Olive. My grandfather was Olof Petter Hake from Trade Lake, WI. I have the plat that shows the property owned by your Olaf Hake and owned by my grandfather. They were supposed to be related but unfortunately I never asked how. My cousin has tried to trace Olof Petter in Sweden but had no luck.
