My paternal greatgrandfather was Thomas Dann born in 1840 in Burwash. He married Ellen Irving Stuttaford in 1864. His father was Caleb Dann born 1811 Rotherfield.I can trace them back to Thomas Dann born 1720 in Salehurst. A lot of this information appears on the IGI. and some I gleaned from a lady in America whose uncle had got the information from parish records. If you think any of this will fit in with your Danns please let me know.
