There are detective stories in most building names. The Kindred Building on 31st Street is likely named for U.S. Rep. John J. Kindred (1864-1937), a Virginia native who moved to Queens and was elected to the House of representatives, serving from 1911-13 and 1921-29.
For a few decades in the 20th Century 26th Street was named for Kindred, as this 1946 Hagstrom indicates. It had previously been called Merchant Street. Neighboring Crescent Street, because it bends somewhat in its journey through Astoria, has never been given a number.
Vallone and Vallone is a general practice law firm founded in 1932 by the Honorable Judge Charles J. Vallone (narby PS 85 is named for him). Son Peter F. Vallone served as Speaker of the NYC Council, and Peter F. Vallone Jr. was a City Councilman from Astoria from 2002 to 2013.
