Thanks for replying - Yes this is the right family
Looking for possible father of the children.
Elizabeth has 4 children - none with a father named. She dies sometime in the 1850's in Copmanthorpe, York as a charwoman.
Census records say she is unmarried.
James' father on his marriage cert is listed as William Fletcher.
Louisa's father on her marriage cert is listed as Joseph Fletcher.
Both these men are more likely to be Elizabeth's brothers - all born Bishopthorpe.
