Thanks to everyone for information received. I now have marriage certificate of Nellie Hooper It says her father was Henry James Hooper , commercial traveller but he had died before marriage in 1930. From the certificate I know Nellie was born about 1906 So if the family found in 1901 census could be located in 1911 census or later electoral rolls and there is a Nellie mentioned. Then this family is mine If not will have to locate another commercial traveller called Henry James Hooper. Thank you. Eirwen
