My great-aunt is buried in Idaho. She has two tombstones--one a military one and other a joint stone with her husband.
The dates of birth and death are the same--born in 1910 and died in 1990.
One has her name as Anna M. Hutchison and the other has her name as Margaret M. Hutchison.
Never hurts to change those first and middle names around when performing searches.
And the stones should be transcribed they way they are inscribed. Commentary about what is "correct" can be made elsewhere.
