Name	State	County	Township	Age	Birth	Month	Cause
Stroup, John C.	Ohio	Holmes	unk	57	GR	Jun	unk

The official enumeration date was 1 Jun 1850, so a death in "Jun" meant June of 1849 (had he died in June of 1850, he should have been enumerated as still living on June 1st).  If John was 57 in 1849, he was born in 1791 or 1792.
