Uh, no, the parent comment explicitly said the Bengal famine of 1943, which had up to 3.8M deaths

The famine of 1876-8 in addition to being worse from the percent-causalities view, and a lifetime earlier (65 years), was also not centered in Bengal but in other regions of India generally further south and west. Different in time, place and severity, and different in the policy response in part b/c the 1943 famine was during WW2.

Uh, this is the Bengal famine the parent comment refers to, right? Ireland has never had 58M people in it.
