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.
