Some historical (mostly Presidential) tidbits:

George Washington
During Washington's lifetime (1732 – 1799), there were thirteen past, present, and future Presidents alive. Other than his own, Washington only saw one Presidency, that of his successor John Adams.
 * 1) John Adams served as Washington's Vice President. They had known each other since at least 1775, when Adams helped appoint Washington Commander-in-Chief of the Continental Army.
 * 2) Thomas Jefferson served as Washington's Secretary of State. They had known each other since at least 1769, when they both served in the Virginia House of Burgesses. They might've known each other before, as they both came from aristocratic Southern Virginia families.
 * 3) James Madison was a leading member of the House of Representatives during Washington's Presidency. They had known each other since at least 1787, when they both served in the Constitutional Convention. They might've known each other before, as they both came from aristocratic Southern Virginia families.
 * 4) James Monroe was Washington's Ambassador to France. They had known each other since at least 1776, when they both fought in the Battle of Trenton. They might've known each other before, as they were both aristocrats from Westmoreland County, Virginia.
 * 5) John Quincy Adams was Washington's Ambassador to the Netherlands. It is unknown when they first met, as Adams spent most of his youth overseas with his father, away from Washington in the US. They likely met at least in 1789, when his father became Vice President under Washington.
 * 6) Andrew Jackson was a member of the House of Representatives very briefly during Washington's Presidency. There's no known sources or information on whether they ever actually met, although it's plausible.
 * 7) Martin Van Buren was between 6 and 14 years old during Washington's presidency, and was still living in his native New York. It is extremely unlikely that he ever met George Washington, as his first known political activity was in 1800, after Washington's death.
 * 8) William Henry Harrison mostly served as a frontier officer, lieutenant to General Anthony Wayne, during Washington's Presidency. As his father, Benjamin Harrison V, had served in the Virginia House of Burgesses with Washington, and both families were aristocratic Southern Virginians, it is possible that Harrison had met Washington in his youth, although nothing states it either way.
 * 9) John Tyler was born during Washington's Presidency (1790) and spent his entire youth in his native Charles City County, Virginia. He came from a powerful Virginian family with his father being a Court of Appeals Judge, so it's possible, albeit unlikely, that he met Washington at some time. He more than likely attended Washington's funeral, though.
 * 10) James K. Polk was born during Washington's Presidency (1795) and spent the last four years of Washington's life in Pineville, North Carolina. Although his father was a slaveholder and a surveyor, the Polk family was still quite poor and it is extremely unlikely any of them ever met George Washington, definitely not in the period from 1795-1799.
 * 11) Zachary Taylor was between 4 and 12 years old during Washington's presidency, and was still living in his native Virginia. His father, Richard, had served as a Colonel under General Washington during the Revolution, and it's possible, albeit unlikely, that he met Washington as a very young child at some point before Washington's death in 1799.
 * 12) James Buchanan was born during Washington's presidency (1791) and spent his childhood living in his father's hotel in Mercersburg, Pennsylvania. Extremely unlikely he ever ran into George Washington before his ninth birthday.

John Adams
During Adams's lifetime (1735 – 1826), there were nineteen past, present, and future Presidents alive. Other than his own, Adams only saw five Presidencies, that of his predecessor George Washington, and his four successors (Thomas Jefferson, James Madison, James Monroe, and John Quincy Adams).
 * 1) Thomas Jefferson served as Adams' Vice President. They met at the First Continental Congress in 1775.
 * 2) James Madison had retired from the House during Adams' presidency, although he was a public opponent of Adams' Alien and Sedition Acts. It is unknown when they first met, as Adams' was overseas during much of Madison's early political career. Madison was a protege of Jefferson, so it may have been as early as 1775, or as late as the 1790s, when Madison and Adams both served in the federal capital in Philadelphia. They were both present at Jefferson's inauguration in 1801.
 * 3) James Monroe was Governor of Virginia during Adams' presidency, which relocated to Washington, DC during his term. He was sworn in as a US Senator by Vice President Adams in 1790. As a close friend and former student of Thomas Jefferson, it is possible that Monroe met Adams prior, but probably not until after Jefferson's return to America in 1789.
 * 4) John Quincy Adams was Adams' first-born son and was Adams' Ambassador to Prussia. It is not known if he was present at his son's birth (July 11, 1767), as was a travelling lawyer and Selectman, but he was definitely known to the child before September of that year, according to letters written by Abigail Adams.
 * 5) Andrew Jackson was a Congressman and Senator for Tennessee during Adams' first year as President. It's likely they would've met in Philadelphia that year, but I cannot find any sources confirming this.
 * 6) Martin Van Buren was between 14 and 18 during Adams' presidency. Although his political career began in 1800, it was situated in New York until long after Adams' retirement, and it's unlikely they ever met. Van Buren was a US Senator when Adams died in 1826.
 * 7) William Henry Harrison was appointed by Adams as Secretary of the Northwest Territory and later Governor of the Indiana Territory. His father, Benjamin Harrison V, was a delegate to the Continental Congress and fellow signer with Adams of the Declaration of Independence, so it's possible they met during Harrison's youth.
 * 8) John Tyler was between 6 and 10 during Adams' presidency, but was the son of a prominent Virginia Judge and friend of the Jefferson family. It's possible, but unlikely that he met Adams during some function with his father, but very unlikely at any point after 1801.
 * 9) James K. Polk was born in North Carolina and less than two years old when Adams became President. It is very unlikely he ever met President Adams, and he only national politics as a Congressman shortly before Adams' death.
 * 10) Zachary Taylor was between 12 and 16 during Adams' presidency, and there is no evidence that they would've met at any point.
 * 11) Millard Fillmore was born during Adams' presidency into a relatively poor family, and would not leave the northern New York area until after Adams' death. They never met.
 * 12) Franklin Pierce was born after Adams' presidency, in 1804 in New Hampshire. It's very unlikely he ever met the retired President, even though his father (Benjamin Pierce) had been a Revolutionary War veteran from Massachusetts and fought in the Battle of Bunker Hill.
 * 13) James Buchanan was between 5 and 9 during Adams' presidency, and spent his childhood in Pennsylvania, many miles from Philadelphia. Although he was a Congressman beginning in 1821, I can see no reason why he would've ever met Adams during his lifetime.
 * 14) Abraham Lincoln was born in 1809 to a poor Kentucky family. He was 17 when Adams died, and had never been to the East Coast at that time. They never met.
 * 15) Andrew Johnson was born in 1808 to a poor family in North Carolina, that later relocated to Tennessee. He never met President Adams.
 * 16) Ulysses S. Grant was 4 years old when Adams died, and still living in his birthplace of Point Pleasant, Ohio. They never met.
 * 17) Rutherford B. Hayes was 3 years old when Adams died. They never met.
