I did quite a lot of work on mine a few years ago. A lot can be done online, but there's an awful lot of legwork involved aswell.
I got pretty much all branches back to about 1700.
Sadly, there was no family money discovered. Schlepping around some areas of Toxteth, Everton, Cheshire, Rochdale, Blackpool, Wigan and Northern Ireland raised many concernes about my alloys wheels.
