Thanks Treetotal, I'm sure you're right about the bracelet.
Was the wearing of Whitby jet popular among all classes or only among the higher classes at this time? I'm wondering whether this and the knuckle ring are indications of Anne's status...
Painting in exchange for services is an interesting idea; as for it being painted by a family member, we've found nothing to suggest any artistic tendencies in our family researches. I'm no expert but to my eyes the portrait seems relatively accomplished, and the gilt frame might also suggest a professional job.
