All somewhat puzzling. As I see it this Fox Dawson "line" came from the relationship of Joshua Fox (Huddersfield 1810) and Amelia Dawson, who married in 1870 after many children, including a Christiana (1853) These were all concentrated in Holmfirth. Joshua had been married before, children include William, Joseph and Nancy. Some clues point to a connection e.g. Holmfirth and the name Christiana and some are against a connection e.g. Leeds, different children names and Joshua birthdate of 1825. This Joshua was on the 1881 census. What do you think ?
