Hi Graham.
In researching the Perriam / Perram family from the Cullumpton area of Devon, I did come across a marriage for a Robert Perram to a Mary Broom on the 30/04/1749 in Cullumpton, Devon. Unfortunately as yet I have been unable to find any research as to if this Robert Perram has any connection to our family, however my research does continue.I hope that this information may be of some help.
