If you can get to Kew, you might find the divorce file interesting. The ones I've seen have copies of the marriage cert, the statement of the aggrieved party, and affidavits to confirm it all - usually fewer than 10 sheets of paper. Other names can show up, as well as addresses and so on. They are not electronic, you need to ask for the original document and you'll find that the file you seek comes in a box with some tens of others.
