FWIW I actually could not find this info, in a quick popular-science-level search.  If it's a dupe (which I could not find), thanks for the pointer.

You can't locate them that accurately. They may have come from a number of constellations. You can find maps easily enough, but I haven't found one with constellations marked. https://www.ligo.caltech.edu/image/ligo20160211b

In which two constellations, were the two gravitational wave events of 2016?

The data is indeed very uncertain. As for GW150914, [LIGO posted](https://www.ligo.caltech.edu/image/ligo20160211b) this image of the probable area of the sky:

[![Black hole merge event location](https://i.sstatic.net/j6EZsm.jpg)](https://i.sstatic.net/j6EZsm.jpg)

The most probable banana-shaped region stretches from Crux to the [Large Magellanic cloud](https://en.wikipedia.org/wiki/Large_Magellanic_Cloud). Comparing the image with a constellation map, there are several small constellations that may have hosted the event. Those are [Mensa](https://en.wikipedia.org/wiki/Mensa_(constellation)), [Chamaeleon](https://en.wikipedia.org/wiki/Chamaeleon), [Musca](https://en.wikipedia.org/wiki/Musca) and [Crux](https://en.wikipedia.org/wiki/Crux).
