LSD Ancestor Hunt might find something if there are at least one or two "dead people" that can be identified.

Living persons are not generally published in genealogical data/sites, so identifying the author may not give you much help with locating living descendants/survivors.

If it's not too remote for you to make contacts, the place of death might lead to a mortuary with a record, and a place of burial might show who paid for the burial plot. A newspaper record/obit would likely list survivors, but there are few places where you can find them without paying fees.
