Hi there
A POSSIBLE match on IGI (familysearch.org) is a christening of a Thomas Dobson, 9 Dec 1743 St Peter, Bolton le Moors, parents Griffy Dobson & Mary. Griffy & Mary also had Alice csd 2/12/1740 and Wm. 3/7/1747 again St Peter's. There is another child Elizabeth csd 17 Mar 1732, St Peter's - parents Griffy Dobson and MARGT. MANN (wonder if the Margt. might have been mis-read and it should be Mary?).
No parish register entries on IGI for either "Griffy" or Mary in Bolton le Moors christenings/marriages, but there is a church member submitted record (not always accurate or based on fact) of a GRIFFIN DOBSON (or (LEVER), born 17 Nov 1704, csd 19 Nov 1704 St Peter's. parents Thomas LEVER and Alice DOBSON (Alice and Thomas do appear in both Thomas's childrens names - could be a co-incidence of course).
May not be right but it's a start
Good luck
