I googled georgia vital records and unfortunately the state didn't keep records that far back.
I see in the 1920 census that the youngest child is only seven months old and was born in south Carolina. Minnie is a widow so her husband may also have died in south carolina.
South Carolina dose have records for that time. If you haven't done so already try https://www.familysearch.org/
It's free and they have a lot records.
