What stands out about Brooklin’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Brooklin was originally part the larger town of Sedgwick. Brooklin broke off and formed its own town in 1849. A few weeks later, the name was changed to Brooklin, after the brook line which separated it from Sedgwick. Using pogie oil as a fertilizer, the difficult soil was made productive, and hay became the principal crop. With excellent harbors, however, the main occupations were fishing and seafaring. By 1859, when the population was 1,002, it also had five boot and shoemaking factories, as well as two barrel manufacturers. By 1886, the town was noted for producing smoked herring in considerable quantities. Canning lobster had also become an important business.
