Yes there are several cemeteries - and some are in St Jacob which is so close to Troy that you do not realize your not there. We have Isenbergs in different ones. They were always poor and so I do not think any headstones exist anymore. I checked at Troy's clerks office while my dad was still living - believe it was about 92 - anyway they didnt have a lot of records for our family. Dad and I walked over what looked like land that had no one burried there - and yet his parents were there. Very sad. So not sure how much luck you will have. I may be able to find out more later since I have a cousin who finally is helping and over at St Paul's Lutheran to see what death records she can locate. Helen in flooded LasVegas!
