Jensey? (Brinson) Fore (1860's FL)

Looking for the parents/siblings of Jensey? Brinson.She was born 1860-1880 in Lacota? (Marion Co FL)? Or somewhere in surrounding counties.All info comes from my husband's 82 year old grandmother - she is not too sure of anything anymore.I do know that there was a large contingent of Brinson's who moved to that region of FL during the 1840's -1850's.I do know that she married a William Fore bef 1896 as her daughter Ada Lee was born in that year.William was also from the same area.Does anyone out there have a clue who this woman was?My husband's grandmother only remembered that she died of a rattlesnake bite in the early 1900's.The rest of her family was from the same area (Lacota).I have been unable to identify Lacota as a geographical area for Marion County FL, but have found other towns she mentioned for her family there previously.Any help will be appreciated.Leigh Anne
