Heraldry on the BBC – Waking the Dead

Whilst watching a recent episode of the BBC’s “Waking the Dead” I noticed some heraldic stained glass in one scene. Using the marvellous BBC iPlayer I managed to get this screenshot;

The story line has the location as a convent in Ireland. However, I dare say the BBC’s location budget puts the building a bit closer to London.

Now to identify the five sets of Arms and the building.

My start;

Window – L to R	Blazon	Armiger
1	Argent two bars wavy between three eagles displayed Azure	.
2	.	.
3	.	.
4	Gules two chevron(el)s Argent	.
5	Argent three mullets Azure within a bordure Sable	.

A Dutch Seal?

A request for assistance from Mark Aronson, Chief Conservator of Paintings, at the Yale Center of British Art. One of the pictures on display in their current exhibition – Seascapes: Paintings and Watercolors from the U Collection is;

Adam Silo (ca. 1674–1772), Dutch shipping off the Low Countries, 18th century, oil on panel

On the back is a seal they would like help in identifying.
