Lu (鹿) is a relatively uncommon name that is not listed in the Song dynasty classic text Hundred Family Surnames.

[1] According to the second-century Eastern Han text Fengsu Tongyi, Lu (鹿) originated from Ji (姬), the royal surname of the Zhou dynasty.

A descendant of Kang Shu was enfeoffed at Wulu (五鹿, northeast of modern Puyang, Henan), and this branch of the Wey royal house adopted Wulu as their surname, later shortened to Lu (鹿).

[2][3] Kang Shu is generally revered as the founding ancestor of the Lu (鹿) surname.

[2] During the Xianbei Northern Wei dynasty, Emperor Xiaowen (reigned 467–499 AD) implemented a drastic policy of sinicization, ordering his own people to adopt Chinese surnames.
