Edward Blewett's commercial ventures included livestock trading, mining, banking and real estate. In 1885, he was reported to have claimed that, "We have the largest horse ranch on this continent, if not in the world." He expected his company, Oregon Horse and Land, to "brand close on to 11,000 horses" that year. He served as president of the First National Bank of Fremont (1888-1890). With others, in Seattle, Blewett founded the Blewett Gold Mining Company, which acquired the Culver Company in 1892. The new company developed the mine and mill along Peshastin Creek in the
Wenatchee Mountains and formed the now-abandoned mining town of
Blewett, Washington, near what is now called
Blewett Pass. Ownership conflicts of the successful mine were ultimately settled by the Washington State Supreme Court in 1913 in Hadley v. Washington Meteor Mining Company. Edward and Carrie Blewett are also credited with helping to develop the Seattle community of
Fremont, named after their hometown. On March 20, 1888, they purchased a parcel of newly cleared land at the northwest corner of Lake Union for $55,000. With the help of their agent, Luther H. Griffith (also from Fremont, Nebraska), the Blewetts' revised plat was recorded by King County on May 8, 1888. Blewett was also president and a trustee of the Van Anda Copper & Gold Company. As of 1897, it was mining on 774 acres of crown-granted land on
Texada Island, British Columbia. The associated mining town of
Van Anda is still inhabited. == Personal life ==
