Hi-Many of the older Cemeteries - only had wooden markers - which overtime deteriorate - perhaps some at this cemetery as well.
We had been searching for the graves of my grandparents 3 daughters -we have now determined that they passed away between 1904 when the youngest at the time was born -and prior to the 1906 Census.
Death Registrations have not been found - the surname CHMELYK is often misspelled.
When we had our Family reunion in 1999 101 years after our grandparents arrival. We did visit a Ukrainian Catholic church cemetery in the area - with 0 success.
There were stone monuments - as well - some wooden crosses still survived.many areas with no markers - but - this cemetery was very well kept.
Again, Wishing you much success with your project.
