My great great great grandmother was called Hannah Ferry and was born around 1849. I believe she was from the County Durham or Sunderland area. She married a man called Thomas Ferry who was born in 1844. They had 6 children, Annie (born 1874), Robert W, Joseph, Emma, Isabella and Margaret, most of whom were born in Fence Houses, County Durham (near Hutton le Spring) or Middlesbrough. This may be the Hannah Ferry you are looking for. She is buried in Middlesbrough.
Please let me know if you have any other details regarding the Ferry family from the North-East.
