Zepave and Liyiyi
Elves, sure, but they were married. And both died in the same year they were married. Starved to death. I can only imagine that they were crowded in their starvation, two lovers, and gave each other their vows before promptly dying this slow, prelonged death.
Mim and Togi
Mim was killed by a Twilight Monster, just a year later the widow he left died of starvation.

I can't find history on how her husband died, beyond knowing that after his death she began wandering the depths of the world, taming random creatures, such as rutherers. She then starved to death.
Theres also the record of an Elf princess being smashed to bits by a Cyclops..
And Upu, who had a couple pages of encounters she narrowly escaped, until after her husband died, then she just kind of was struck down by a simple night monster, where so many beasts had failed. Dragons, Cyclops..
I cant seem to find the specific one of a human spouse being killed by an ettin, the other spouse wandering the wilderness until they die of starvation and then their one year old child dying of starvation as well.
Its just, there are so many dead elves.. and so few living ANYTHING. other then titans, lots of living titans. its mostly dead elves and dead goblins, some dead humans a few dead dwarfs. But they all starved to death, had family members starve to death and then die to a megabeast, or everyone starves to death then their children are killed by a megabeast, or all three happen at once. And reading the descriptors of what they take to doing after their families are slaughtered.. they just start roaming the world. Under or overworld, until some tragic end befalls them.
edit: not to say scores of dead elves are bad, of course.
