Are These Pictures Possible? #2 - Historical Figures

After my magazine's animal range fiasco, I decided to release an issue focused on pairs of contemporary historical figures. My writers drafted illustrated stories on pairs of historical figures whose lives overlapped. I was about to publish the issue when my intern said 15 of the stories are inaccurate since the lifespans of the historical figures did not overlap. Can you identify which images show individuals whose lives didn’t overlap?
