Mckha489 does appear to have
already found a living great grandchild, so that's one option. Whether the family would be interested is another matter though.
I'll start putting a tree together on Anc over the next couple of weeks although it may be sometime before Anc index it (it can take a few months). It's a bit of a long shot but some descendants might find it and I can direct them to this thread (if you still have the item by then).
As for other descendants, I'll follow up on the children of Frederick, as there may be some there with the Tilling name, so may have more interest.
