The name Mullennix arrived in England after the Norman Conquest of 1066. The Mullennix family lived in Lancashire. The name however, is a reference to the family's place of residence prior to the Norman Conquest of England in 1066, Molineaux-Sur-Seine, near Rouen, in Normandy.

Early Origins of the Mullennix family

The surname Mullennix was first found in Lancashire as "an ancient Norman family, who have been possessed of the manor of Sefton, in this county, from the period of the Conquest, or very soon afterwards: it was held as a knight's fee, as of the Castle of Lancaster." 1 William de Molines was the first recorded ancestor. "Previously to the Conquest, 'Sextune,' one of the original parishes of Lancashire, was held by five thanes. The family of Molyneux or Molines subsequently settled here. William des Molines, so named from Moulines, a town of Bourbonnois, in France, is mentioned in the Norman Chronicles as a man of noble origin, held in high esteem by the Duke William, afterwards William I. of England. In the roll of Battle Abbey, his name stands the eighteenth in order; and soon after the Conquest, he acquired, by gift of Roger de Poictou, the lordships of Sefton, Thornton, and Kerden, of which he made Sefton his chief seat. " 2

We now wish to draw the reader's attention to the township of Netherton in the parish of Sefton. "Sir William Molyneux, who received the honour of knighthood in the 46th of Henry III., gave by a deed without date, to William, son of his brother Roger, certain lands in Netherton, to hold by knight's service and the yearly rent of one halfpenny; and Sir William, a member of the same family, gave lands in Netherton to his son, John, about the reign of Richard II. The township is still the property of the family of Molyneux." 2

Over in Kirby more records of the family were found. "Adam de Molynes, lord of Sefton, in the reign of William II. married Annotta, heiress of Benedict, son of Roger Gernet; and this place has ever since remained in the family of Molyneux, of Sefton." 2

The parish of Altcar in Lancashire has an interesting feature of the family's history. "Little Altcar is a hamlet adjacent to Formby; and Altcar Hall is an ordinary farmhouse, over the door of which were formerly the arms of the noble family of Molyneux." 2

"Croxteth Hall, [in West Derby, Lancashire] formerly called Barret's Hall, the chief seat of the earl of Sefton, is situated in this township on the borders of Croxteth Park, from which it takes its name. The Molyneux family acquired it in Henry VI's reign, when Sir Richard Molyneux was steward of the manor, and about 1540 was one of the chief residences of the Molyneux family." 3

Mullennix Spelling Variations

A multitude of spelling variations characterize Norman surnames. Many variations occurred because Old and Middle English lacked any definite spelling rules.

Therefore, one person was often referred to by several different spellings in a single lifetime. The various spellings include Molinieux, Molinaux, Molineaux, Molineux, Molinex and many more.

Migration of the Mullennix family

Many English families left England, to avoid the chaos of their homeland and migrated to the many British colonies abroad. Although the conditions on the ships were extremely cramped, and some travelers arrived diseased, starving, and destitute, once in the colonies, many of the families prospered and made valuable contributions to the cultures of what would become the United States and Canada. Research into the origins of individual families in North America has revealed records of the immigration of a number of people bearing the name Mullennix or a variant listed above: James Molinex settled in Philadelphia in 1685; Edward Molineux, who arrived in Virginia in 1719; Jonathon Molineaux, who came to Maryland in 1726; Samuel Molineaux, who settled in Philadelphia in 1846.
