From Find-a-Grave.I have been unable to find out where Alexander M. DeBree was buried. Most likely it would be in Norfolk, Virginia, but also possible is that he was buried in Pensacola where his wife and child are buried.
CHARLOTTE ELIZABETH DEBREE Born 1837 Died October 22, 1858
Gravestone reads that she is the wife of Alexander M. DeBree.
There is also a Charlotte Louisa DeBree, born 1858 and died Jan. 16, 1859 buried in the grave.
I believe this to be his wife and daughter. Evidently, he was stationed in Pensacola at this time if they are his wife and daughter which I believe them to be.
