Theodore Roosevelt became president when William McKinley was assassinated. Chester Arthur became president when James Garfield was assassinated. Lyndon B. Johnson became president when JFK was assassinated. Andrew Johnson became president when Abraham Lincoln was assassinated. But I assume you are referring to John Tyler, whose nickname was "Accidental President" or "His Accidency". He became president just 30 days after President William Henry Harrison died. Harrison's death was attributed to his giving the longest inaugural speech in history at the time, and did so without wearing a hat, causing him to fall ill and die just 30 days later.

John Quincy Adams was the first president whose father was still alive when he ran for president.

The president does not have a son. This is a very frequently quoted internet rumor, with no facts to support it. On the other hand, the president's father (whose name was also Barack Obama), did have a son-- and that is the man who became the president in 2008.
