Looking for Priscilla Roof - could be a different spelling - perhaps roofe, rouf, rauf, roff, rolf or rolfe.
She was born around 1839 reputedly in Gloucetershire or Wiltshire, but I have been unable to find out any information about her. It is possible she came from abroad.
She married a John Smith and had a number of children including John, Maria, Henry, Priscilla and Freedom. Her husband John was born in Coleford, Forest of Dean, Gloucetershire.
Any information would be welcome.
