Hi Foz,
I have been trying for a long time to find a link to this side, I am on Genes Reunited - and have a tree on there.
They (Wyatts) came from the small 3 villages of Otmoor and Islip area of Oxfordshire 6 miles N/E of Oxford.
They are mentioned in Court Rolls going back to 1426 at least. I have actually seen these originals myself. There is a box of Wyatt land records of my direct line from the 17th & 18thc in an archive library.
Look forward to any information, especially if any pre WW2 photographs exsist!
Best
Andrew
