A portrait of his man can be seen at Philipps House in Dinton Park, Wiltshire. But my question is What relation was he to the families who lived at Dinton Park?

I also have an interest in Sir William Chapple, as in his will, which was proved in 1855, my 4xgt-grandfather James Willing, bequeathed to his daughter Ethelinda, “the portrait of my ancestor Judge William Chapple”. So far I have not been able to establish any family link.

Why not come to Philipps House (Dinton Park) and take a look at the portrait. We are open on Saturday mornings (starting March 31st this year) and on Monday afternoons. The house was pretty well unfurnished when the NT took it over and, apart from a few Wyndham and Phllipps relics; has been furnished by them and the tennants Mr and Mrs George. Hence the presence of an unrelated picture kn the Dining Room where all the others are of the Philipps family. Visitors do ask about the judge, hence my enquiries here. I am glad, as one born in dearest Dorset, to learn that we have a Dorset man in the Wiltshire dining room. Ivor Stacey (Room Steward).
