Hi,
www.familysearch.org is giving a christening date of 30 Apr 1766 in Hutton, Lancashire.
I think it is a submitted record so will need to be double checked. No mention of parents names though.
http://www.genuki.org.uk/big/eng/LAN/Hutton/This is the marriage from
www.lan-opc.org.ukMarriage: 5 Feb 1794 St Helen, Garstang, Lancashire, England
John Hornby - Batchelor of Garstang
Alice Mayor - Spinster of the Chapelry of Goosnarg
Witness: Thamas [sic] Harrison; Mary Bradshaw
Married by Licence by: James Fisher Vicar
Notes: [Groom signed John Horndy, Bride signed Alice Mayor]
Register: Marriages 1781 - 1802, Page 124, Entry 507

I think even if you checked the original, the fathers names were not recorded back then so I think you best hope is to try and check the original christening record.
You could try Lancashire Records Office at Preston. If you can't visit in person they will help by email and if they have the record will photocopy it for you but there will be a charge.
