The history of Sister Bay has been a growing one since the first settlers immigrated here in 1857. At that time the village of Sister Bay was part of the Township of Liberty Grove, which was founded in 1859. As the northern part of the county grew, other settlements rose and fell. Sister Bay continued to progress to its present status of an incorporated village with 1960 census citing a population of 520.
Sister Bay, as it has always been known, although called Big Sister Bay at one time, was named in connection with the Sister Islands that flank the harbor opening to Sister Bay. It has come a long way since those first settlers of Ingebrett Torgerson and the Dimond brothers, Thomas and Pat. In April of 1912 the citizens petitioned for a right to become an incorporated village. Fees of $14.00 were paid by Henry Graass.
The early settlers families are very memorable today, as some of their descendants are in the third and fourth generation of inhabitants in the area. Among the Ericksons, Andersons, Kellstroms and Roesers, the Roeser name is probably the most remembered one.
