There is now an extensive and authoritative biography for him on Wikipedia which can be found at this link. Rather than repeat that here follow that link. Briefly however:
Alexander Hamilton was born circa January 11, 1755 or 1757 (the exact date is unknown), on the island of Nevis, British West Indies. He was born out of wedlock to James Hamilton and Rachel Fawcett. His father was the son of a Scottish Lord. In 1777, Hamilton became General George Washington's assistant.
In 1788, he convinced New Yorkers to agree to ratify the U.S Constitution. He then served as the nation's first secretary of the treasury, from 1789 to 1795. On July 12, 1804, in New York City, Hamilton died of a gunshot wound that he sustained during a duel with Aaron Burr. 
In the Hamilton Y-DNA Project, known descendants of Alexander Hamilton have been assessed as Group I1-5 Haplogroup I1a2a1a or I-Z140. So in order to be a male line descendant of his, you need to have the same genetic result. At this point none are on Wikitree. 
To date one of his descendants on Wikitree has completed an autosomal test.
Previously there were extensive extracts presented here as notes including a copy of the letter from Burr to Hamilton in 1804 an the text of Hamilton's speech to the Federalists in 1804. These have been converted to a PDF file and can now be found under the Images tab and headed "Some General Notes".
Eight U.S. states have named counties in Alexander Hamilton's honor. They are: Florida, Illinois, Indiana, Kansas, Nebraska, New York, Ohio, and Tennessee.
