Hi Chad, good to hear from you and hope that you are keeping well over there in the USA.
It has been quiet on the Jones front and I've not heard anything about the Jones side of the family who are in touch with someone else from the States. I've recently had contact with my friend who knows the Jones family and I'll see him in the pub sometime and ask him about the Jones'.
I can't help you to find the grave of Annie Maria as I've already had a look at the Burial Indexes for Llandudno. They only show graves with headstones anyway so if Annie didn't have a headstone then she wouldn't be in it.
I've also looked at Billion Dollar graves but again Annie does not appear there. Her death was recorded in the September quarter of 1909 at Solihull in the West Midlands so yesterday I looked at some of the Cemetery records for Solihull but without any luck.
There has got to be a record of the burial and the most likely place to have it must be Solihull but where do you start looking for it?
It might be worth looking at the Solihull Heritage Forum as I read about someone in the same position as yourself looking for a grave.
I've attached the link for you and hope that you can get the answer you are looking for and in the meantime if I do hear anything about the Jones then I'll post it on here.
