Until 1789 Inzenhof belonged to the Parish of Heiligenkreuz and from 1789 on to the Parish of St. Emmerich in Oberradling (Felsö Rönök) - you should find the birth record for Cecilia on the LDS-film from Rönök 1789-1895.
I do have some headstone pictures for the name Jost from the cemetery of Inzenhof (birth dates starting 1862)
