No visit to this topic is complete without these facts;
1) William Henry Harrison, 9th President USofA, 2 February 1773 to 4 April 1841, was POTUS for 31 days, shortest term on record. Oldest elected President (68) prior to Ronald Reagan (69), gave 2 hour inauguration speech in the rain and cold. First President that was Grandfather of a President, Benjamin Harrison (1833-1901), 23rd President.
2) John Tyler (1790-1862), 10th US President and 1st VP to fill office for death of predecessor. Lost most of the Presidential Cabinet (chosen by Harrison & Henry Clay) as most believed he should only be a caretaker fill-in. Former Democrat-Republican but anti Andrew Jackson and switched to Whig Party after Federalist Party died. Most children (15) of any US President, by 2 wives, with 1st born in 1815 and last in 1860. His Virginia home, Sherwood Forest Plantation, is still owned by his grandson, Harrison Ruffin Tyler (92).
The Harrisons and the Tylers lived across the street from each other, I think.
