Wikipedia

Today in class I had the idea of my entry being on my Uncle's company stared by my Grandfather. I looked it up and there were quite a few entrys so I limited it by adding the city and there were no entrys. I made sure I could find information on it by searching google with the eact wordin I searched Wikipedia and sure enough there it was. In conclusion I have found my entry. Now my only question is if you are placing personal knowledge of the company how do you do that?
