Our surname study grew out of the Wiley DNA Project at Family Tree DNA, which began in 2003 and has grown to over 350 members. Y-DNA testing revealed that men with different variations of the surname that previously had been considered distinct and separate names surprisingly were closely related genetically and shared a common ancestor within a genealogical timeframe. In contrast, some members who shared the same surname spelling were found to have completely different Y-DNA signatures, indicating descent from different paternal ancestors. Exactly how and where the surname originated was unclear, with many theories being suggested. Multiple origins seemed likely. A closer examination of the history of the surname and the development of its variants was indicated.

A Facebook group for our surname was begun in 2015. There we encouraged members to share genealogy, photos, stories, records, pedigrees, DNA results, and anything else related to their genealogy. Our collection of information began to grow and experts in the genealogy of our surname were attracted to the group, enriching the quality and quantity of the research.

In 2021, a surname study was commissioned from cartographer/genealogist/surname specialist Howard Mathieson, who runs The Geography of Surnames website.  Through the extensive collection, analysis, and correlation of data, Howard produced a series of maps illustrating the frequency and distribution of the Wiley/Wylie/Wyllie surname through time, across Britain. It soon became apparent that the surname had a focus in Ayrshire, Scotland, which tallied with what the DNA results had shown. As a result, that location was intensely studied.

With data from the DNA Project, the Facebook group, and Howard Mathieson’s analyses accumulating, we realized that we needed a central place to (1) archive our work so that others could benefit from the efforts of the many descendants and researchers who had labored over the years to learn about the surname and its history and (2) to provide a platform for future research endeavors. And thus, the Wiley One-name Study was registered with the Guild in 2022. The choice of which spelling would be the main one and which would be designated as variants was a difficult one and could be debated, but Wiley was eventually chosen for the study title because it corresponds to the name of the Wiley DNA Project, which started this whole ball rolling.

Multiple geographic origins in Britain have been proposed for the surname Wiley/Wylie/Wyllie. Suggestions for its origins are almost as numerous as its spelling variants.

England
The name has several proposed topographic sources in England, most notably in Wiltshire, where Wylye parish appears in the Domesday book. The Oxford Dictionary of Family Names in Britain and Ireland suggests that its etymology is linked to the River Wylye. In reference to the river, the name Wylye (pronounced why-lee) is described in The Place Names of Wiltshire as of uncertain etymology. It might mean tricky stream, they venture, but the authors are of the opinion that the word has no connection to the adjective wily, as is often suggested. The river gives its name to the county and perhaps to the local inhabitants under the Saxons. The tribal name of the people who lived around the Wylye in the ninth century was “the Wilsætan, or dwellers by the Wylye.” Wiltshire, as an administrative unit, was in existence within what would become its medieval boundaries by the end of the eighth century. To complicate matters further, other English locative origins have been suggested from various places, such as Wyly in East Hoathly (Sussex), Whiligh in Ticehurst (Sussex), Weeley (Essex), Weoley (Worcs), and Willey (Cheshire, Devon, Herefordshire, Shropshire, Surrey, Warwickshire).

Scotland
The name was used in ancient times by the Strathclyde-Briton people of the Scottish/English Borderlands. George F. Black’s Surnames of Scotland identifies it as a diphthongized form of Willie, a diminutive of William. By the late 16th century, surnames had been in use in Scotland for 200 to 300 years, and hereditary surnames, like DNA, would be carried forward by each generation to the present. Wylie (Wyllie), a patronymic surname, would be established in Scotland in regions where William was a common forename. As record-keeping and the maintenance of parish records became standardized, we can see the surname take hold in scores of locales. For example, an early bearer of the name lived in Dumfries in 14th century Scotland, where today the name is typically spelled either Wylie or Wyllie. By 1700, major core areas were well established in Ayrshire, Kincardineshire, Angus, the Lothians, and Fife.

Ireland
Also common in Ireland, noted Irish surname scholar Edward MacLysaght identifies the origin of the surname as Scottish but also acknowledges its English locative sources. He claims that it came to Ireland at the time of the Plantation of Ulster at the beginning of the seventeenth century and is now numerous there, especially in County Antrim. The Wylie spelling is common in Ireland, as is the anglicized Wiley spelling.

Hopefully, as our study progresses, our research will bring more evidence and clarity to the story of our surname’s origin.
