Carolyn, When Anna died in 1897, death records were supposed to have been filed at the county courthouse. The death record contains the person's name, marital status, age, sometimes the deceased's parents' names, the place of death, the cause of death, the place of interment, the date of death, and the date of interment. Try to get a death record from the Beaver County courthouse for Anna and you will most likely find Thomas too. Of course, they may not have headstones. Good Luck!
