From Wikipedia: w:Thomas Hallifax:

Sir Thomas Hallifax (1722-1789), of Gordon House, Enfield, Middlesex, was an English banker, Lord Mayor of London and Member of Parliament. He was born the younger son of a Barnsley clockmaker and moved to London, where he found work as a bank clerk. He rose to be chief clerk before leaving to found a bank of his own, Vere, Glyn & Hallifax Bank, with fellow banker Joseph Vere and merchant Richard Glyn, which later became Glyn, Mills & Co.. He was made an alderman of London in 1766 and elected Lord Mayor of London for 1776–77. He was knighted on 5 February 1773. He was briefly a Member (MP) of the Parliament of Great Britain for Coventry from December 1780 to February 1781 before being unseated on petition but then returned unopposed for Aylesbury to sit from 1784 to 1789.[1] He died in 1789, leaving a fortune estimated at £100,000. He had married twice, firstly Penelope, the daughter of Richard Thomson of Ewell, Surrey and secondly Margaret, the daughter and coheiress of wealthy merchant John Saville of Enfield, Middlesex. He had two sons, Thomas and Savile, by his second wife, of whom Thomas became a partner in the bank.

The Savile-Hallifax family of Chadacre Hall in Suffolk are said to have descended from the Waterhouse family (arms: A pile engrailed sable), when a cadet branch adopted the surname "de Hallifax" from the place of their abode. (Source: Burke, Sir Bernard, The General Armory, London, 1884, p.444). Chadacre Hall was sold in 1918 by the Hallifax family to the 1st Earl of Iveagh, of the Guinness brewing family. Arms: Quarterly of 4:

• 1&4: Or, on a pile engrailed sable between two fountains three crosses-crosslet of the first (Hallifax) (a difference of Waterhouse. In both the Dictionary of National Biography article on Bishop Samuel Hallifax and in "The Worthies of Barnsley" on his cousin the banker Sir Thomas Hallifax it says that their family came from Halifax, West Yorkshire, and that their name had originally been Waterhouse);
• 2&3: Argent, on a bend sable three owls of the field (Savile).
  

Impaling: Quarterly of 4:

• 1&4: Argent, two chevrons sable a bordure engrailed of the last ( Godfrey? - not given in Burke's General Armory);
• 2&3: Or, three bends gules.

The new grant of arms was a difference to those granted to a certain Robert Hallyfax of Yorkshire on the 9th of October 1573 by Sir Gilbert Dethick, which omitted the crosses crosslet.
