It could very well be. The only information I have is that my father remembered his father saying that some of their ancestors came to Kentucky from North Carolina. I have record of John Washington Davenport marrying Cinthia Walker in Kentucky but do not find any birth records for John Washington Davenport in Kentucky. I have also found the surname spelled as Devenport. Please let me know if you think there could be a link to your John Davenport
