What drives Bombay’s History grade
On its age, its old homes and the National Register, Bombay is more historic than 59% of U.S. towns. Its age holds the grade up; its National Register listings pull it down.
B
HistoryA character grade: shown, never part of Bombay’s overall grade.
New York towns list more on the Register than most of the country (a typical New York town has 12.3 per 10,000 residents, the U.S. 2.4), so Bombay’s 0.0 sits below most of its state (10% of New York towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to A−. The pre-1940 share is a Census survey estimate (±11.5 points). The founding year is the first post office, not a stated founding date.

What stands out about Bombay’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Bombay is named for the wife of Michael Hogan, an Irish ship captain who grew wealthy in the East India trade. He came to the US in 1805 with his wife, whom Hogan said was an Indian princess.
Hogan bought 20,000 acres (81 km2) north of the Adirondack Mountains, including the Town of Bombay, which was named in honour of his wife's birthplace. Their son, William Hogan, served as town supervisor, and was elected to the New York State Assembly in 1822. In 1829 he was appointed as a judge of the Court of Common Pleas for Franklin County, and in 1830 he was elected to Congress.
The Bombay post office opened in 1838, the earliest record of the town by name (U.S. post office records).
