Looking for Louise E. Griffith family from Illinois

This woman was my greatgrand mother, I know she was born in randolph county Illinois... I know of two brothers asasph and william riley griffith... all three were born in illinois and died in perry county missouri... I have zero info on her family... will exchange any info..
oh louise E. Griffith married William Thomas Phillips, the known children are:
cleve, esther, nellie, sorry i dont have my info on me right now.. but they had a boy who was grown and out of the home, but he and his wife just had a baby and he came down with TB, so he went home to his mom and dad which at the time lived in Claryville, perry county MO so he could die, grandma use to say that he came home to keep from giving to his wife and baby...she also said she helped her mother take care of him until his death... now my stumbling block is they all called him Buddy, but that was a nickname... I am stumped... thank you for reading this...
