There is a lock of hair from Mary Q o S at Chiddington Castle in Kent, I haven't seen it. At Sudeley, there is also a tooth belonging to Katherine Parr!!
Henry's sister, Mary-Rose had hair of a "beauteous golden colour" and a lock was cut from her head when her tomb was opened in the 18th century. It ended up in the collection of the Duchess of Portland and when that collection was broken up and sold off,it was sold to a gentleman (this was in 1848).
There is another lock of her hair preserved in a locket in the Moyses Hall Museum in Bury st Edmunds. It is possibly very slightly darker in colour than that of Katherine Parr's.
Last I heard there were plans afoot to extract DNA from this lock of hair with the aim to compare with DNA extracted from "THOSE BONES" kept in the urn at Westminster Abbey. Of course, permission has not been granted for access to "THOSE BONES".......yet.:-)
