The farming settlement established by Collins, Van Asselt and the Mapels was originally known as "Collins". 

Luther Collins, who was named the County Commissioner and appointed himself road supervisor for all of King County, routed the main road from Seattle to Tacoma to go right by his house.  The road led to a ferry, called the Collins Ferry, which took passengers across the Duwamish River.  Fares ranged from 12 1/2  for a "footman" (someone walking) to 50¢ for a man with a horse. 

At some point the settlement became known as "Dwamish" which was the name of the Post Office established there in 1874 (and also name of the native peoples who lived here). 

The Horton brothers Julius and Dexter, arrived in 1871, and purchased 160 acres of Collins' original claim.  The brothers were very different in personality but both were very ambitious.  While Dexter was against the drinking of alcohol, his brother Julius saw the possibilities of making money through the brewing business and land development.
