I tried as well, finally eliminating her first names. There were 16 trees, all of which appeared to be private. That could be why none of them seem to show up.
There was an owner for a tree for Jean Domenica Chasteauneuf, born in France (no date shown). This tree says it has no sources.
There are public trees for persons with the same last name (but not first name), born between 1915-1925, with the birth locations of England (Sussex, London and Kent), as well as another with a birthplace of Clark, Washington, USA.
Good luck.
