I am aware that there are a number of early church fathers who made this connection (e.g. [here](http://www.ccel.org/ccel/schaff/npnf201.iii.vii.xvi.html) and summarized [here](http://coldcasechristianity.com/2014/is-marks-gospel-an-early-memoir-of-the-apostle-peter/)). Is there also material internal to Mark's gospel to suggest that it reflects the memoirs of Peter?
