Specifically I am looking for the graves of Joseph Curbow (Revolutionary War soldier) who died in 1850 and his wife Mary Corbin Curbow who died in 1839. They were living in Gwinnett County at the time of their deaths....so I made the assuption that the church/cemetery would be in Gwinnett County. I have recently learned that it may be in Barrow County, Georgia? Any guidance would be appreciated.
