About the study

The Mon(n)ington One Name Study began with a search for the extended family of my wife'€™s ancestors. The project was registered with The Guild as my second ONS in 2000 when the opportunity of an impending move opened up the prospect of local research.

Variant names

Monnington and Monington were used interchangeably before spelling became standardised. Mannington seems to be centred on Sussex and is believed not to be a variant; it is the subject of a separate ONS but is frequently confused in records.

Name origin

The name may be locative. I am aware of two locations in Britain, Monington in Pembrokeshire, Wales and Monnington on Wye, Herefordshire. There is also mention of Monnington Straddel a now deserted village in the Golden Valley in Herefordshire, where some believe Owain Glyndwr is buried. Littlebury's Directory and Gazetteer of Herefordshire, 1876-7, referring to Monnington Court, states that '€˜Monnington was the property and seat of an ancient family of that name, who derived it from their residence on this spot....'  The image is of St Mary Church, Monnington on Wye.

The Monnington DNA Project welcomes all participants. We encourage you to join today!.

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.

You can learn more about this significant research, and the associated family trees, by visiting the one-name study web site, or contacting the Group Administrator.

Monnington One-Name Study

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 Monnington 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.

Both males and females may also be interested in learning about their direct female line, which would be their mother, their mother's mother, and back in time.  Both men and women inherit mtDNA, although only women pass it on.   To explore your direct female line, you would order a mtDNA  test.  For matches in a genealogical time frame, order the mtDNA Full Sequence test.
