Hi Teresa,
Johnson Braxton Galey (or sometimes John B.) was the son of Andrew Galey and Martha Isbell. His siblings were Nancy, Rebecca, Martha, Jeptha Vining Galey, Jabez Isbell Galey, Godfrey, Dandridge Thompson Galey, and Clarissa.
Martha Isbells parents were Godfrey Isbell and Hannah. Her siblings were Robert, Sarah, Jeptha Vining Isbell, James Milton Isbell (probably), Jabez Isbell, and Clarissa. So you can see quite a naming pattern going on with this family.
Hope this helps!
Heather
