I've been searching for my grandfather, Patrick Connolly, aged 24, born Widnes since the 1901 census went back online after it was re-launched and at long last I've located him.
He was working/living in Manchester and appeared on the census web site as Patrick Elly! I discovered this by omitting his surname and searching only on 'Patrick', age and place of birth. I'd seen Patrick Elly a number of times before ( I'd gone round in circles, repeating the same searches!) without it occurring to me that this was my grandfather.
A few days ago I made yet another fruitless search and it suddenly dawned on me that Patrick Elly and Patrick Connolly may be one and the same and when I paid to see the image of the actual written page I saw how the mistake had occurred: his name had been written as Patrick Conn Elly and 'Conn' had been omitted from the transcription.
Another of my families, Hatchell, was listed on the 1901 census as Hatchill, on the 1881 as Matchell.
Keep searching and use your imagination!
Rosemarie.
