The family appears to come from Arbory. LDS film number 0106706 to look at copies of the parish register to see whether more information is given for the children's bapts., for their marriage, and for burials.

You need John Moore's age and place of birth from the 1851 census to trace him back.

Brian's burials have: MOORE, Anne aged 50, Arbory, on 5 Feb 1845. [PRESTON]

This could be her bapt [from IGI] ANN PRESTON Christening: 08 DEC 1794 Arbory: Father: WM PRESTON, Mother: ISB CAUGHIN.

There are two John Moore bapts in Arbory, either of which could be his, in 1781 and 1788 [IGI]. The census will give you a clearer idea.
