Edward Blewett's commercial ventures included livestock trading, mining, banking and real estate.
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.
In 1904 the Blewetts moved to the Echo Park neighborhood of Los Angeles, California, living on West Kensington Road until their deaths: Carrie's in 1927 and Edward's in 1929.
