          "In 1686 the town granted \"mill rights\" to John Pine, who dammed Milburn Creek near today's Milburn Avenue and Merrick Road to build a gristmill; the mill drew farmers to settle nearby and a community began.[2] During the Revolutionary War, British troops occupied the area for seven years, from the Continental Army's 1776 defeat at the Battle of Long Island until 1783, requisitioning fencing, firewood, crops and farm animals from local residents.[2]",

Baldwin, a builder, horse and cattle breeder, one-term New York State Assemblyman and three-term Queens County Treasurer — had become prominent local landowners and benefactors; the historical society's history states plainly that \"the members of the Baldwin family had done so much for Hick's Neck that the village was named Baldwinsville in their honor.\"[3] The U.S. Postal Service later shortened the name to Baldwins to avoid confusion with Baldwinsville in upstate New York; local usage settled on Baldwin.[1]",
          "In 1910, brothers Albert and Arthur Heinrich, who lived near today's Plaza School, \"are believed to have built the very first successful all-American powered monoplane\" and flew it for the first time that year, later building improved aircraft.[5] Baldwin's population grew from about 5,000 in 1920 to about 12,000 by 1930.[5] By 1939, according to the historical society, Baldwin was \"the largest unincorporated village in all of New York State with over 4,000 homes and 119 apartments,\" a distinction it held until Levittown's growth surpassed it around 1960.[4]"

Today it is called Merrick Road.\"[2]",
          "In 1929, \"the new Sunrise Highway became the major east/west route through Baldwin. This solved some of the traffic problems of the old Merrick Road, which was often jammed with cars on weekends.\"[5] Sunrise Highway is New York State Route 27; NYSDOT's touring-route description carries NY 27 on Sunrise Highway through this stretch of Nassau County's South Shore.[6] That same year, 1929, a small aircraft company took over the old plane factory on Brooklyn Avenue and grew into the Grumman Aircraft Corporation, later a major Long Island aerospace employer.[5]"
