Best way to organize data?

I have a quick question that I have been trying to come up with the best solution for. I built an app that stores some data. It stores an array of name and each of those names have and array of events. At first I thought a 2D array would be my answer but it’s not, since the first index of the name array should tell what data the 2nd (events) array has to offer. Can anyone point in me the right direction for dealing with this kind of information?

Thanks
