Hello Anne.
I have been in touch with Tom Driver, but like you recently tried to contact him again and the e-mail was rejected.
However, as you can see I am an Exeter, but so far I have only been able to trace my family back to the Sevenoaks area of Kent. There are still a lot of Exeters in the Dartford Area but I cannot find any connections yet. So far I have gone back to 1705.
If you have any info on Exeters I would be glad to exchange info with you. Perhaps some of my info on Sevenoaks Exeters would be of use to you.
Regards
Peter Exeter
