Just out of interest, I had a look back to see if the 2 girls in the 1901 census were at the end of a long family, as has happened in my family (one child born 24 years after his eldest brother and 13 years after the previous child). In 1881 Joseph Clark(e) of Maisemore was a widower, so Emma must have been a second wife. Unfortunately there are quite a number of Joseph Clark(e) marriages to Emma (unknown) between 1881 and 1885 (birth of Ellen), so no way of tracing her back. None of the marriages are Gloucester or Kidderminster.
