Chinese emperors family tree (early)
Emperor Xian, the last emperor of the Han dynasty, was a descendant of the first emperor Liu Bang. Lasting for over 400 years (the first to last for more than a century), the Han Dynasty is regarded as one of the golden ages of Chinese history. The Han Dynasty was interrupted by the reign of the usurper Wang Mang, who declared the Xin dynasty (9–23 AD); on this basis, the Han Dynasty is generally divided into the Western Han (206 BC – 9 AD and 23–25 AD) and the Eastern Han (25–220 AD). The rulers of the Shu Han, one of the three successor states to the Han Dynasty during the Three Kingdoms period, were descended from the Han imperial family, and considered themselves a continuation of the Han Dynasty; they are included below.

Regarding the words Late Han, Siku Quanshu Zongmu Tiyao (四庫全書總目提要)
argued that "presumably, Wang Can died when the Han dynasty still existed.
Though there were so many symptoms that the Han dynasty was near its death,
Emperor Xian still was on the throne. Wang Can surely could not use the words 
of Late Han as the title of his book, therefore Late Han 
is thought to be introduced by the future generations.
However as Wang Can described Cao Cao as holy ruler (聖君) in his book 
"A Poem of Military Service" (從軍詩), we cannot not say with full certainty that Wang Can
did not put Late Han in the title of his book".
