Looking for record of death on Louisa Jane Barrett Jackson. The first name may be spelled differently, I've seen 3 spelling variations Louisa, Louiza & Luzia.

She was married to Robert H. Jackson in Dawson County GA in 1861. They had one child Homer Robert Jackson born in September 1861. Robert H. died in 1863 in a RR accident in Meridian Mississippi. The child can be found living with relatives by the 1870 census. I'm trying to determine what happened to Louisa. I know Louisa died between 1861 & 1870.

If anyone has access to death records for this time period I would greatly appreciate a lookup for this information.
Thank you in advance.
