Some of the transcriptions on Ancestry are done very badly.  When I started out, I used the 1901 census on the national archives site and found my greatgrand father.  On ancestry they have a very poor image.  My G Grandfather on ancestry has ?? for his first name, and his middle name was wrong.  His sister was transcribed as Elizabeth when she was Isabella.  Try searching for different spellings.  I was searching for a Dennis Turvey and it turned out he was transcribed as Donnis Turney.  One of my ancestors was transcribed as being aged 3 and a wife, when infact she was 23.
