Notes and queries: the Dann family

“I have just discovered that on the 1901 census that my great great grandfather James Dann was living at number 40 Livingstone Road with his wife Ann. At the time of the census, there were no children. Does anyone remember them? I do not know how long they lived there for, but it wouldn’t have been long after this date as they were in Desbury, West Yorkshire, in Nov 1901. James’s father was also called James and his mother was Monalois. James also had a sister of the same name as mum but on the 1881 census they were all living at King Street brighton. Does anyone know anything about them?”
