This is what I've got which maybe your William and family:
parents
Father: ? ( why no fathers name)
Mother: Hannah Tolley
William Tolley Christening: 23 SEP 1821 Upton Warren, Worcester
Ann Tolley Christening: 17 NOV 1830 Upton Warren, Worcester
John Tolley Christening: 24 NOV 1824 Upton Warren, Worcester
Parents
Father: William Tolly
Mother: Hannah
Hannah Tolley Christening: 27 APR 1800 Upton Warren, Worcester
William Tolley Christening: 22 JUN 1806 Halesowen, Worcester (interesting)
There is another possible birth for William
William Tolley Christening: 01 JUN 1821 St Andrew, Droitwich, Worcester
What do you think Steve.
I'm sure other people will be able to expand further for you Steve because I'm not sure where we go from here and why isn't a father listed on the IGI? The IGI isn't my strong point

Regards
Adrian
