There is a Robert L Craig listed on the 1920 Seneca,Newton County, Missouri census. He is 65, estimated birth year is 1854, born in Tn. R L Craig is listed on the 1930 Seneca, Newton County, Missouri census, He is 75. My GGrandfather was Isaac Craig, born in 1812 in Tn. He moved to Greene County Illinois in the 1850's and then on to Newton County Missouri in the 1870's. He died in 1898 in Seneca and is buried in the Bureson Cemetery. There were two Isaac Craig's listed on the 1880 Newton County Missouri census and so far I have not been able to connect the two families together. Your R L Craig could belong to one of these families or both.
