Parents: Richard (Middle name may be Arch per 1820 census. Many family trees list him as S. Richard...however, this likely began from his will where the "I" Richard looked like "S") and Lanah (Bennett) Flowers
Siblings:
1. Isaac Flowers

2. William A. Flowers, Sr.

3. Mary (Flowers) Wickiser

4. Rebecca (Flowers) Morgan

5. Hannah (Flowers) Arnold b. abt 1812 (Hannah is NOT a sibling. Hannah Flowers has been linked as being married to Morgan Darnell rather than as the marriage certificate has Morgan Arnold. Hannah that has been linked to this Flowers' family doesn't appear that she is listed in the 1820 census; nor two lists of Richard and Lanah's children) I am leaving Hannah here only to show that she is likely not a child of Richard and to hopefully stop the addition of her to family trees.

6. Richard Flowers

7. Alexander Flowers

8. Elizabeth (Flowers) Hare, McClintock

9. John Flowers (b. abt 1820)

10. George Flowers

Additional History:
The Vicksburg cemetery records were lost in a fire, but the newspaper, which published the Sexton's Report, is a wealth of information on who was buried in the City Cemetery, i.e. Cedar Hill Cemetery. There was a Holding/Receiving Crypt built on the grounds in 1858 to hold bodies for interment, a few were shipped home for out of State reinterment, but most buried in mass graves there. During the Yellow Fever and Diphtheria epidemic, there was a huge number of bodies the City of Vicksburg had to deal with. No refrigeration invented yet. Out in the country, many were buried on the farm, but in the city they were placed in the cemetery. Many were just passing through on the Mississippi River Steamboats, got sick and died, so were buried in Vicksburg.

Vicksburg, also had one of the few Hospitals in the State, which was built in 1832.
In 1871, there were so many people in the State of Mississippi coming to the Vicksburg City Hospital that the City of Vicksburg asked the State for funds. They got the Funds and renamed the hospital Kunn State Hospital.
