I want to research my family's geneology, but I only have information
on the past three generations - too recent for many geneology websites
to list.  My grandparents are all deceased, and I have no older
relatives.  I also live out of the family's original area and so am
unable to access parish records and the like.

Question - is there a way to research my geneology online starting as
recently as my parents or grandparents generation, and working
backwards?  If so, what/where is it?

(Please bear in mind I'm in the UK, and so not all american websites
are applicable!)
