Squires, Squire or Squier?

From the Squire Family Ancestry and Descendants of David Squire 1743-1821 and Mary Bunker in the DAR Library, Washington, DC: About 1600 the family was split along political views. They were referred to as 'the Squires' meaning everyone collectively. Those within the family known as the Roundheads - supporters of the parliamentary party in England - continued with the spelling Squire. Those known as the dissenters - the nonconformists - changed to the spelling Squier. In reviewing genealogies at the DAR Library, both spellings can be found in the same lineage. Even our own Ephraim Hiram has been attached to Squire, Squires, and Squier.
