These types of disputes happen all the time, in REALTOR circles as well as among neighbors. This happens especially since certain "neighborhoods" have more prestige (read: wealth, value) than others, and this can affect the perceived value of property.
There's an interesting discussion of this issue on the Chicago Architecture Blog:
The post describes two maps that the city maintains for its own purposes: a "Neighborhood" map and a "Community Area" map. The latter "Community Area" map is the one that we REALTORS depend upon to categorize our listings in the Multiple Listing Service.
The Community Area Map actually represents historically contiguous areas that were developed more or less during a particular period of time. The Neighborhood Map outlines areas of the city, some smaller than one Community Area or straddling two Community Areas, that represent the effect of certain ethnic, cultural, or community groups on the organization of our city. Neighborhood areas typically focus around a church, school, park, or other institution with which the residents identify. Community Areas, on the other hand, oftentimes delineate areas that may have once functioned as separate towns or villages that were eventually annexed into the city proper, for example, Hyde Park, Lake View, Jefferson Park, Rogers Park, Austin.
Developers and REALTORS are always coming up with new ways to describe our neighborhoods, though, so expect to be surprised!

The name Goose Island may have originally referred to a small natural island at the north side of the confluence of the North and South Branches of the Chicago River that was home to seasonal flocks of birds. In the late 1840s the surrounding area was on the fringes of Chicago and a group of Irish immigrants started squatting on the unoccupied land around what is now Kinzie Street, between Franklin Street and the river. This settlement may have been known as Kilgubbin (or kilgobbin), named after the area of County Cork, Ireland that had been the former home many of the immigrants. The squatters eventually moved the Kilgubbin settlement a short distance north to an area on the east side of the river between Chicago Avenue and Division Street, on site of the present-day Goose Island. The original Goose Island had been dredged away by 1865.
The land that was to become the present-day Goose Island lies on a bend in the Chicago River between North Avenue on the north and Chicago Avenue on the south. In 1853 William B. Ogden, who had been Chicago's first mayor, formed the Chicago Land Company, which purchased land on the east side of the river to excavate clay for brick-making. Starting from the south, workers excavated a channel northwards, and by 1857 the channel had rejoined the river forming a shortcut past the bend in the river. The channel was eventually dredged to 50 feet (15 m) wide and 10 feet (3.0 m) deep to make it navigable, and it became known as the North Branch Canal, or Ogden's Canal. The island thus created was also sometimes nicknamed Ogden's Island, a name that some Chicago aldermen proposed to make the official name of the island in 1891. The name Goose Island, may refer to the earlier location of the Kilgubbin settlement close to the original Goose Island, or it may have been in reference to the flocks of geese kept by the settlers on the island.
The settlers were eventually joined by Polish and German immigrants to the city. For most of the residents, daily life hovered between rural and urban, with many raising livestock while also working in nearby factories. Over 100 units of housing were built in a three-block area to accommodate the new residents. Various taverns and bars also opened, which became the center of activity for the island's residents.[ci
