Stephen Berriman born 1801 Zennor

[lesean]

I am looking to find the parents of Stephen Berriman born Zennor 1801/1802. In the 1851 census record he is living in The Belyars, Halsetown, St Ives and is a miner. He married Ann Edwards 05/04/1829. The baptism of their daughter Mary Berriman was 29/01/1831 at Uny Lelant. Mary Berriman married William Lobb 22/05/1850. In 1851 they are in the Census living at The Beliers St Ives with their son William Lobb age 6mths. Their son then married Grace Vibart  in 187 and they emigrated to New Zealand. 
Mary Berriman should be in the 1841 census age about 10 but I can't find her.
Her father Stephen Berriman I think could be a sister to my 2nd great grandmother Philippa Stevens Berriman born to Henry Berriman and Grace Stevens Berriman Zennor 1818. I would greatly appreciate any further information on Stephen Berriman. Thank you

Stephen Berriman was baptized at Zennor 1st April 1804 to Henry Berryman and Grace Stevens who married at Towednack 27th January 1798.

Not sure why you can't find Mary in the 1841 Census but it may be a problem with the transcriptions provided for the Census index. It could also be that she was with relatives or the family of a friend on Census night. Another possibility is that her age has been mistranscribed - this often happens either because the handwriting is poor or the area of the page is faded or damaged but it can also be caused by marks made by Census officials when checking off details.

There is a Mary Berryman of about the right age at Phillack in 1841. She is not with family but because birthplace is not recorded in this Census it is extremely difficult to determine exactly who she might be.

Be aware also that, as with many other families, the spelling of the surname varied. You may have a man signing his signiature as 'Berryman' when married but the same man might sign as 'Berriman' when he witnesses another document or when he writes his Will. And the spelling definitely varied in BMD registers depending on when, where and by whom the document was written.
