A Swedish family has letters written to their Swedish ancestor from Mill Creek MI in 1902 and 1903 by a relative, Emanuel Engstrom. Was the town of Mill Creek on the site of the present Mill Creek Historic Site?Emanuel (Eriksson) Engstrom was born in Sweden in 1882, came to the U.S. in 1902 and wrote that he worked in a tannery in Mill Creek MI. His Swedish friend, Olof Albert PERSSON, who came with him, also worked at the tannery. I can find no reference to either of them in the 1910 census. Does anyone have any suggestion as to where I should look for information?
