The Lu clan and the Sun clan had a rather tumultuous past. Even though Sun Jian had once helped a member of the Lu clan secure his territory from bandits, Sun Ce badly defeated Lu Kang. Some time after Sun Ce's death, a certain Lu Yi entered the employ of Sun Quan and was noted for his talent.
When Sun Ce's daughter was wed to Lu Yi/Xun, it was to help bury the hatchet between the two clans. For reasons I'm about to detail below, I believe that the decision to wed the daughter of the man who'd soundly defeated the man that raised him was made by Lu Xun himself.
Let's take a look at Lu Xun's given name.
遜
This is a rather unusual name - xun means modest or to abdicate. However, as modest as Lu Xun is, I believe that the reason he chose this inauspicious name was not for the meaning of the character, but for the symbolism behind the character.
The main component of 遜 is 孫... Sun. As in Sun Ce, Sun Quan, Sun Jian, et cetera. The radical of 遜 is 辶, which is the "walking/traveling" radical.
The symbolism behind this character could be:
Given that Lu Xun, in my opinion, changed his name to signify that there were no hard feelings between his clan and the Sun clan, it may be that he petitioned Sun Quan to marry him to a woman of the Sun family to further signify the end of hostilities between the two clans.
