Did you receive any info on John W. Davenport? Forgive my mistakes at this; I am new to this forum.
John W. was my gg-grandfather; his son James A. Davenport, m. Sarah Henderson, was my g.grandfather; their son George Caspar, was my grandfather; his son, James A., was my father.
After several years of research, I've only found the record of John and Cynthia's marriage. But my brother has a fairly good record of descendents.
Hope to hear from you!
