In 1840 census I show: Dandridge BushFree Colored living in Springfield Twp1 male ,1 female between 24/36 I also found a burial in Greenlawn Cemetery , Chillicothe for : Isaiah Bush s/o Dandridge and Rebecca Bush died 9-17-1849 at 3yrs7das. So it appears that Dandridge was apparently alive as late as 1846. Here is bad news I found Rebecca Bush listed as living in the Poor House in the 1850 Ross County Census. I found no burial record for Dandridge or Rebecca Bush. I still am short a couple of local cemetery books , when I purchase them I will look for Rebecca and Dandridge in them. Good Luck . Keep the family alive by remembering those who are gone.
