I have a problem with an elusive grandfather. Joe SIDDORN was born 17/12/1881 in Tarporley, Cheshire so just missed out on being included in the 1881 census. He did appear in the 1891 census when he was still living in Tarporley with his parents Joseph and Ann SIDDORN. By the 1901 census Joseph was dead but Ann SIDDORN was still living at the same address in Tarporley but Joe was no longer there and as far as I can see appears to have disappeared into thin air until he resurfaces in Birkenhead in 1908 when he married Alice STOTT. Obviously I would love for someone to get back to me and tell me that they have found Joe in the 1901 census but realistically what I am asking is for opinions as to the most common reasons for people seeming to disappear. Military service, prison, travel abroad, totally different spelling of the name, simply slipping through the net? What are other peoples experiences? Thanks, Alan
