William Mobberley was lord of the moiety of Mobberley and patron of the Mobberley church. He bought the moiety of Nether Poever from Richard Bonstable in 1281. He had William, John, to whom his father gave all his lands in Nether Poever and Tatton, but John died sine prole and those lands reverted to William. Another son, Richard, was made parson of Mobberley by his father, but was slain by another Richard Mobberley. William Mobberley died about the beginning of reign of Edward II, 1307.
