Who What Where Research genealogy services can help you to begin to research your Family History project, or to continue the journey. I am based in London but also specialise in researching Welsh ancestors. I pride myself on trying to add extra information to enhance your project, such as chronological timelines - putting your family history into a historical context. Each client is presented with a written report accompanied by basic ancestral charts and maps.

I have easy access to all the major London archives including The National Archives at Kew, The London Archives, the British Library and The Society of Genealogists.I also use the National Library of Wales, Ceredigion and Glamorgan Archives regularly.

Being proudly Welsh, I specialise in researching histories in the southern, western and mid-counties of Wales.Coping with the complexities of so many ancestors sharing a common last name whilst being completely unrelated, can present a special challenge. Similarly having knowledge of the area involved can help to avoid geographical confusion!

In additional to Genealogy services, I am also experienced in assisting authors and commercial clients. I am an experienced public speaker and run courses for The Society of Genealogists.

I have a background in History, with a B.A from University College Cardiff. After a gap of many years working in publishing, I happily returned to my natural habitat via the Postgraduate Certificate in Genealogical Studies at the University of Strathclyde. I have been honoured to have been made a Fellow of AGRA in 2026

"Many thanks for the dilligent and painstaking work resulting in a fascinating picture of the family. Much of the material is new to me but some names and places resonate with stories told in the family in years gone by. The wider family will surely treasure this record."

"I was very impressed with the breadth and depth of your report on my grandmother, especially the extra things like maps and pictures: great stuff!"

CP, London

"Thank you so much for the report, which I am now going to pass on to my sister-in-law in Australia. Considering the huge number of people with the same surname in the area at the time, I think you've done a brilliant job in sorting out which are G's ancestors."
