Individual Details

Green C. Baker was a brother to Eliza Emmeline Baker that married Armstead Flynn. Both were children of Robert Clay Baker, born 7 May 1801 in Tennessee, died 25 Aug 1879, Greene Co, IN. Their mother was Sarah Christenberry, daughter of Joseph Christenberry. Sarah was born Jun 20 1806, VA, died 10 Feb 1879, Greene Co IN. Exmon Flynn married Phebe Christenberry, obviously also a relationship among these families.
Online databases also suggest an unnamed daughter born between 1820 and 1825 in Tennessee which fits the profile of Elizabeth Baker who married William Flynn.
