She is in the Forest Hill cemetery in Glen Ellyn, Illinois.  I did a bit of photo manipulation to make the stone a bit easier to read — and I was able to double-check what I thought it said, using    Drusilla VanTassel (yes, just like the VanTassel family of Sleepy Hollow …. ) was the wife of Samuel VanTassel, and died December 17, 1862.   The full inscription read: Wife of Stephen, 52y 6m 19d.      I have checked census records and found no Drusilla VanTassel, although there were 11 Drusillas in the 1860 Illinois census, and I’m thinking she is most likely one of those women.      I also found no Samuel VanTassel in my quick search (although he may turn up if I dig some more).
