I spent a long time a few years back researching my family tree online, and had a great deal of success. However, I tend to forget that more resources are being added all the time.
I have just come across THIS BURIAL & CREMATION RECORDS SITE, which may be very useful for any of you who are also interested in genealogy. I have found quite a few London rellies on it - it will need visiting at regular intervals I feel, to see new stuff as it is added.
Free search, but only a pay and go at present to look in more detail. Hope it helps.
