Ownership data

Anyone know where I can find who the top 5 owners of a certain public company were in a certain year ?

That is, I would input a year and a company, and the top 5 owners with # of shares/pct. of shares owned would pop up.

by the way, by "top" I mean those who have the largest holdings in the company. If you know where I can get this info for a specific year, that'd be great, but having the information just for 2014/2015 would be useful as well...

Thanks

EDIT: please look at comment below because I'm answering part of my own question...
