You're right I wasn't aware of their projects on the census. But that was partly why I posted the message, hoping someone would tell me of something like this. But I'm surprised I haven't been linked to it before. Anyway, I need to go back and see what exactly it consists and whether it does what I'd like. The big thing I'd want would be being able to find the same family in consecutive censuses without having to do a lot of work.

Any, thanks much for the tip.
