Hi Susan
Sorry, I don't have access to any census sites, but the IGI has one or two possible siblings:
Bessy Awty chr 17th April 1831, daughter of Thomas Awty and Sarah (C039621) Adwick le Street,
George Auty chr17th Feb 1833, son of Thomas Auty and Sarah (C106761) Skelbrook chapelry of South Kirkby, and
Joseph Auty chr 6th September 1835 (C106761 as before).
I'm a bit confused about the info you give, Thomas being born around 1810 and Sarah 'seven years younger', i.e. born 1817. This would make Sarah (Shillito) only 11 on her marriage to Thomas in 1828.Could you please clarify? Perhaps, if you are going by Sarah's age in the 1861 census, he married twice, each time to a Sarah?
regards,
Lesley
