Ernest was born in Georgia, perhaps Mitchell County, the son of Asa Bryant Joiner and Susan Ellen Davis Joiner, and was raised there.
In the 1900 US Census, he is listed as living with his parents in Branchville, Mitchell County, Georgia, and his occupation is listed as farm laborer.
In the 1920 US Census, he is listed as living with his family in Sylvester City, Worth County, Georgia, and his occupation is listed as a laborer in an oil mill. From his Sep 1918 World War I Draft Registration Card, we know that he was working for the Planters Oil Company in Sylvester, manufacturing cotton seed oil. It also tells us that his eyes are blue.
He married Sarah Jane Alderman some time before his draft registration.
Before 1931, his family removed to Miami, Dade County, Florida. It appears that his parents also removed there with them. In 1931, he is working for the Seminole Drug Company.
In the 1940 US Census, he is listed as living with his wife in Miami Springs, Dade, County, Florida, and his occupation is listed as merchant working on his own account.
He was living in Miami Springs when he died in 1964.
