The SSDI transcription states a death date of 16 May 1978 in Jefferson County, Kentucky for John F. Oregan, aged 73, which matches the claim's date and county. The age fits the 1904 birth year. As an index without an image it cannot confirm the full middle names or the burial, and the county may be the residence rather than the death place. The research note says Find a Grave agrees on the date.
Matches: Name OREGAN, JOHN F. matches John Francis Xavier O'Regan (spelling variant, middle name abbreviated); Death date 16 May 1978 matches the claim exactly; Jefferson County, Kentucky matches the claimed place; Age 73 at death is consistent with a 1904 birth (73 in May 1978 implies birth 1904 or 1905)
Limits: Index entry only, no image of the record; SSDI gives only the initial F., so it cannot confirm Francis Xavier; SSDI place may be the residence or last benefit location, not necessarily the place of death; Burial at Calvary Cemetery comes from Find a Grave, not this record; Citation has no URL, and the research note says a different Find a Grave memorial was rejected, so identity depends on the Find a Grave match
