I'll modify mine a bit to include where I actually live, and the largest nearby city, which is probably more well known.
1. Give us your locale
Marcellus, NY. A small town of about 6,000 in upstate NY. Likely named after Marcus Claudius Marcellus, a Roman General. Several towns / cities in the area are named after Roman cities or individuals. Although no one has heard of the town I live in, it is a suburb of:
Syracuse, NY, also located in Onondaga county, and definitely more well known.
2. What are you known for
Marcellus: Not a thing. I live in a very small town, which is exactly how I like it. I live here because it's really quiet, safe, and is close to lots of outdoor stuff to do. A particularly productive trout stream is only a couple minutes from my house.
Syracuse: Syracuse University, and snow. We average around 115" of the white stuff annually. University is pretty well known for it's basketball program, and for generally being a good institution.
3. Famous people
Marcellus: No one famous here.
Syracuse: Tom Cruise, Bobcat Goldthwait and Richard Gere lived in Syracuse, but more famous people are connected to the University. Ernie Davis, Jim Brown, Carmelo Anthony, Bob Costas, Donovan McNabb, Joe Biden (Vice President of the USA) and several others went to SU.
I personally think the history of the area is more interesting than either of the cities. Onondaga county, which both Syracuse and Marcellus reside, is an area formerly inhabited by the Iroquois (Native American) Nation. During the early 1600's when the area was being colonized by European settlers, the previously separate Iroquois tribes joined together to form the 5 Nations, under the guidance of the peacemaker Hiawatha (yea, the guy from Civ 5). As part of his plan to achieve peace between the separate nations, Hiawatha encouraged the leaders of the 5 tribes to bury their weapons along the shore of Onondaga Lake (now one of the most polluted in the US, yay!) as a symbolic gesture of them putting down their arms. Supposedly that was the origin of the phrase "to bury the hatchet" - or putting aside differences for a common good.
