Name origin

According to -

Recorded in many forms including Liddiard, Lidiard, Lyddiart, Liddeart, Liddiert, Lidierth, and others, this is an English medieval surname. It is locational from either the village of Lydiard in the county of Wiltshire or Lydeard in the nearby county of Somerset. In the famous Domesday Book of England in 1086, Lydiard is recorded as Lidiarde, and Lydeard as Lediart. The second element of the name was originally 'garth.' This is an old English and Welsh word meaning steep hill, and both places are situated by prominent hills. The first element is not proven, but may mean be a short form of the pre 7th century 'hylde' meaning a river. The surname is first recorded in the early half of the 16th Century in the reign of King Henry V111th (1510 - 1547), and early church register recordings include that on August 5th 1539 of William Lyddyard. He was christened at St. Andrew's Ogbourne in Wiltshire, whilst Elizabeth Liddyard married Robert Bradley, at St. Mary's Marlborough, on December 4th 1607. Other recordings include Elizabeth Liddiard, christened at St. James Clerkenwell, city of London in 1623, and in the north of England Margaret Lidierth was married at Liverpool, Lancashire, in March 1838 (volume 20, page 213, civil registration index). 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.

The Liddiard DNA Project welcomes all participants. We encourage you to join today!.
Our website is at

Our project is just getting started, and we expect to have many exciting discoveries.

Participating is an opportunity to uncover information not provided in the paper records, which will help with your research of your family tree. We will also discover which family trees are related. As the project progresses, the results for the various family trees will provide information on the evolution of the surname.

The surnames in this DNA Project are researched as part of the Liddiard one-name study. You can learn more about this significant research, and the the associated family trees, by visiting the one-name study web site, or contacting the Group Administrator.

The Y DNA test tells you about your direct male line, which would be your father, his father, and back in time. You must be male to take this test, and you should have one of the surnames shown. If you believe there is a Liddiard or variant in your direct male line, although you have a different surname, you are also welcome to participate. If you are female, you will need to find a direct line male in your family tree to participate and represent your tree.

We encourage males to order a Y-DNA test for 37 markers, if possible. If you order less markers, you can upgrade later, though this costs a little more.
