Can a galaxy be a member of more than one constellation?

How so and what are some examples?Can a galaxy be a member of more than one constellation?No, you have it backwards.

The stars we see as formations called constellations all belong to the Milky Way Galaxy.

Distant galaxies are catalogued separately and are NOT a part of any constellation. The human eye was responsible for conjuring up the various patterns. Only stars qualify as members of a constellation, and ALL stars visible to the naked eye reside within our Milky Way.Can a galaxy be a member of more than one constellation?The IAU divided the sky with lines on charts. These make the classical and modern constellations into 88 areas of sky with the same names. If a galaxy falls right on a border line, it can be said to exist in more than one constellation. However, most of the well known galaxies are inside boundaries. The one exception is the Milky Way Galaxy. Since we are inside it, and it surrounds us, everywhere we look is part of the Milky Way Galaxy. So in a real sense, all the 88 constellation areas of our sky have the Milky Way Galaxy, or at least a part of it. And at least one star of our galaxy is inside each of the 88 constellation areas.Can a galaxy be a member of more than one constellation?The plane of the Milky Way stradles several constellations, and the "outliers" from that plane occupy the remaining constellations.

I am not aware of any other galaxies that occupy more than one constellation, but many do have large angular diameters, so I wouldn't rule it out.
