The name GILLIAM is an English variant of William, from a central French form in which W is replaced by G. William is from the Norman form of an Old French personal name composed of the Germanic elements wil ‘will’, ‘desire’ + helm ‘helmet’, ‘protection’. This was introduced into England at the time of the Conquest, and within a very short period it became the most popular personal name in England, mainly no doubt in honor of the Conqueror himself.
Prior to 1700 there lived in Europe many people with "GILLIAM" surnames. In England were Gilham and Gillam; Gillian, GILLIAM in Scotland; Guillam and Gwillam in Wales and Guillaume in France.
Prior to 1700 the GILLIAM surname appears in Virginia records as Gillam, Gilham, Guilam, Guilham Guillam, Guilliams, Gwilliam, Gwilliams, Gillom, Gillum, Gyllom, and GILLIAM (and undoubtedly other spellings).
GILLIAM is identified by the U.S. Bureau of the Census as a surname with more than 100 occurrences in the United States for the year-2000 U.S. Census. In "Demographic Aspects of Surnames from Census 2000", the Census Bureau tabulated the surnames of all people who had obtained Social Security Numbers by the year 2000.
GILLIAM ranks #1141 in terms of the most common surnames in the United States for 2000.
GILLIAM had 28,075 occurrences in the 2000 Census, according the U.S. government records.
Out of a sample of 100,000 people in the United States, GILLIAM would occur an average of 10.41 times.
All data is derived from David L. Word, Charles D. Coleman, Robert Nunziata and Robert Kominski (2008). "Demographic Aspects of Surnames from Census 2000". U.S. Census Bureau.
For convenience, the spelling GILLIAM will be used unless it is known that a particular person or line prefers another spelling. (For example, the GILLIAMs of Albemarle County consistently used the spelling Gillum.)
Though many GILLIAMs make a three-syllable word of the name GILLIAM (Gil-le-um), the name is most commonly pronounced in Virginia as a two-syllable word (Gil-lum or Gil-yum).
