Hi Sue....what was the daughters name who was born in 1818....if we can find her on Cheshire parish records database(CPRDb) we may be able to work backwards to find Thomas.......allan
IGI says that the baptism were at the Wesleyan Baptist, Preston Brook.
Ann Astbury - 01 Dec 1818 Wesleyan, Preston Brook, Cheshire
Sarah Astbury - 16 Aug 1820 Wesleyan, Preston Brook, Cheshire
John Astbury - 17 Mar 1822 Wesleyan, Preston Brook, Cheshire
Mary Astbury - 28 May 1823 Wesleyan, Preston Brook, Cheshire
Thomas Ashbury - 11 Aug 1824 Wesleyan, Preston Brook, Cheshire
or Liverpool
Daniel Sandback Astbury - 9 Jan 1830 Saint Peter, Liverpool, Lancashire
Elizabeth Astbury - 14 Jul 1831 Saint Peter, Liverpool, Lancashire
Emma Astbury - 13 May 1833 Saint Peter, Liverpool, Lancashire
Frances Astbury - 04 Jun 1835 Saint Peter, Liverpool, Lancashire
There is a Sarah Sandbach baptised at Whitegate 16 Jul 1797, but I cannot see Thomas.
No marriage on the Cheshire Marriage index either.
