This is a name of very great rarity, so rare that it does not appear in the modern London directories at all, although all early recordings are from that area. The "link" spellings would seem to be from "Walliter" as shown, and this is quite conclusive; what is less so however, is the origin. The surname as "Wallet" derives from the Norse-Viking pre 7th Century personal name "Walpeof", which does translate as "the wealthy one", but the suffix "er" suggests a topographical or even job descriptive origin i.e. one who lived or worked at some place in medieval London known as "the wallet". This is quite possible but not proven absolutely. The name recordings include Christopher Wollider (1642), Robert Wallitur (1642) later recorded in 1642 at Waliter, and in 1644 as Wolliter. The first recorded spelling of the family name is shown to be that of Xpofer Walliter, which was dated May 7th 1570, a witness at the church of St. Giles, Cripplegate, London, during the reign of Queen Elizabeth 1, "Good Queen Bess", 1558 - 1603. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
