Hi Haggis Maggie and welcome to Rootschat!!
There is a baptism on the IGI (
www.familysearch.org) for a Mary TABBERN at Warrington Parish Church (St Elphin I think) 23 Sep 1827, Father Thomas, mother Mary batch no: C007978.
There may be a little more information on the actual parish record, if you think this is the right Mary Cheshire Records Office may be able to provide you with the detail if you drop them an email (or a photocopy of the entry for a small fee, you can order online from their website
http://www.cheshire.gov.uk/Recordoffice/home.htm).
There also seems to be a son, William TABERNE baptised at Warrington 10th Oct 1830.
This could be the family in the 1841 census at Meeting Lane, Penketh near Warrington:
Thomas TABBURN, 55, Ag Lab, Y [born in County]
Sarah TABBURN, 20, Y
Mary TABBURN, 15, Y
William TABBURN, 11, Y
Ann TABBURN, 7, Y
John TABBURN, 4, Y
Thomas TABBURN 1 1/2, Y
Hope this is of some help,
Jean
