Looking for info on Louisa Perlina Griffin and Lonnie James Griffin.

I have her as the daughter of Lanier and Sarah Griffin? I have her in the 1860 census with initials P. L. and living with mother Sarah. Can't locate her in 1870, possibly due to another married last name or perhaps misspelled name?

Was she married before John James Jackson in 1877. The 1880 census show Lonnie or James Griffin residing in the Household with her and new husband. I have searched everywhere i can think of and have not found another marriage or spouse for her before Jackson.

Thanks for the help! Jeff
