(Data in italics: retrieved from 1851 Census, Norfolk, England - the census also states that Taylor Leeder was a farmer holding 300 acres and employing 11 labourers).
It has been assumed from the 1851 Census data that Edmund, nephew of Taylor Leeder, must have been the son of Edw. Cots Leeder since none of the sons of Thomas were named Edmund and Jane's sons would have had another surname.
