Hello Hazel. I wont be able to do much research on your Briscoe or Dodd....... I am on my way out of the door to drive to California (my children live there) for Christmas, will not be back much before New Years. In the mean time....... my great grandmother was Sarah Dodd born in Oxton in 1841...... we think. Will get back to you....... Happy Christmas and New Year. Bryan Briscoe-Smith. Colorado Springs.
