Are you familiar with OCR? In this case, although Thomas' obit includes the words "Thomas Wyndham Jones" the "Wyndham" element has NOT been read and captured correctly on the database. Effectively, it doesn't exist.
I had found the item on British Newspaper Archive (BNA) searching for "Thomas Jones", applying filters (County,/Newspaper) and ploughing thru' the snippets returned. To find it on FindMyPast try completing the fields as follows -
Who optional - enter (1)"thomas" (2) jones"
What else? optional - enter "woore"
Date - 1850-1899

Should return 4 hits. You'll notice the 3rd hit refers to "Thomas Jones, Solicitor" but when you read the original (foot of column 1) it reads "Thomas Wyndham Jones, Solicitor"!! I won't go into the vagaries of OCR.
There are half a dozen or so items re. Thomas, mainly adverts, which give his name/office as a contact point.There's also the item about his brief incarceration - although it ends well by noting his assets on release covered his debts.
When searching you need to be flexible. Some items exist under Thomas Jones only - no Wyndham (the original that is, not a question of initial misread problem). I have access to both BNA and FindMyPast. I am comfortable navigating British Newspaper Archive - I am not comfortable with FindMyPast. Both enjoy the same database.
