Before 1546
So, you're fortunate enough to have solidly traced your line back to the beginning of the Wing parish records - congratulations! Now what? Below are some suggestions that might be useful.
This time frame is not my area of speciality - if you are more knowledgeable than me about early records that are useful for genealogical purposes and have some pointers, additions or corrections to make, please don't be shy, let me know.
Feet of Fines
Some legal actions (generally over land) can be found in the surviving Feet of Fines records. I've collated those I have come across that involved Wing here.
Muster Rolls
Muster rolls listed the inhabitants of a village liable to pay for the defensive arms of the village, along with those who actually held the arms. On this website I have transcriptions of the rolls for 1522 (a goodie as it also lists the value of their land and goods) and 1535 (this roll has names only).
Wills
There are 22 surviving wills for Wing residents that were proved in the Archdeaconry of Buckingham from 1483 to 1546. These are held at the Centre for Buckinghamshire Studies - find them in their online index.
