The area was named for a partnerof the founding father of Racine; Gilbert Knapp. There were also several other men who werepartners of Captain Knapp The author of this book says that as early as 1840 the assets of the business were dividedamong the partners.One of his partners Joal Sagecame west early in 1835 met Knapp in Chicago and Captain Knapp encoraged Joel Sage a New Englander to settle in Ragine. Sage estalished his claim to 107 acres; known as (Sagetown) north side of the Root River,west of the land that was taken by Knapp and the other partners. Racine grew as a port at first with businesses lake to land than land to lake. The port was at the mouth of Root River growing to the south, west and north. Monument Square which still existswas an open market place south of the River on Main Street.This part of the city was the hub of Racine.The central area was between Lake Michiganand to the south to Seventh Street. (not a really large area)First it extended north of Root River to areas called "Canada" and "Sagetown". Later south along the lake residential areaswere developed. Builders were using brick as well as wood. Apparently a cream brick was used which is a an apparently rare brick (i have noted a lot of articles about this different brick) Immigrants divided into 3 sections, the north side was called,"Canada", the south side the "School Section"...the west side at that time called "Sagetown."Hope this helps a bit.
