Does anyone have access to the Pencombe parish registers?

Using Genuki and IGI I have traced some of my husband's ancesters.
His grandfather Percy Edward Baker b.1/11/1878, Yarkhill
G grandparents are James Thomas Baker b.30/5/1839 Humber m. 1868 to Anne Lambert b. 1846 Humber. I now wonder if these two were related as cousins.

James Thomas' father was James Baker b. 1795 Pencombe m. Ann Galliers 1838
Anne Lambert's mother was Ann Baker b C1804 Pencombe. Were their parents brother and sister?
From James and Ann Galliers marriage cert I have James' father being James Baker no age
From IGI I have Ann Baker's father being James Baker who married Elizabeth Badger in 1790. I also have several siblings for Ann including a James born Pencombe 1791. Are these two James the same person?
Is there anyone who can prove or disprove my theory
Sorry if this is difficult to understand. I tried to add an attachment, of this part of the tree, but failed!
