What are the names of the 'mom' and 'daughter' from Motherdaughterfuck?

These two were a pair in the mid 2000s. They claimed they were mother and daughter but it always seemed dubious. I never knew if they had names as far as I recall. They don't seem to ever do lesbian acts together, it's usually them joining on a guy. Sometimes another woman would be subbed in for the daughter. Most of their content seems lost to time but they had a website which looked professional and a partial copy is in the internet archives. Any ideas? They must have retired from the business.
