Vivian and his brother, Captain William Molyneux (some records make Captain William the father of Vivian), were in the 1st expedition of the Army sent by William the Conqueror under the conduct of Roger de Poytiers (Poictou), Earl of Lancaster, in 1066. de Poytiers was then possessed of all the tracts of land in Lancaster between the river Robbie and Mersy by gift of the crown, and gave half of land as services of Knights fee as well as the manors of Septon, Thorndon, Kerdon in Co. Lancaster to Captain William Molyneux who made Septon his chief seat. Vivian succeeded Captain William Molyneux to these holdings (whether as brother or as son).
Vivian, after the succession, was placed in de Poytiers castle at Liverpool to act as governor and Castellanus, in the utmost limits of the earldom. He was succeeded by his son Adam.
