This isn't my Fultz family, but along the way I have accumulated a little about non-related families in the course of my own research that I'm glad to pass along if it's of use to anybody.
I have a Louzana Lea FULTZ (5 Oct 1835 - 22 May 1916) married to Thomas Burton BELL (He may have died early.He wasn't on the 1870 census.).This Louzana FULTZ was the d/o Ephraim FULTZ and Ruth MEYERS of Warren Co., TN.They moved their whole family to Osage, Carroll Co., Arkansas.There were also Siscos who came from Warren Co.In fact, Louzana's brother Wilburn F. FULTZ married a Mary Jane SISCO.
Do you have any dates for your Luzana? It's such an unusual name, that it makes me think she could be from this extended family.
