I have recently started tracing my Family Tree. I've had pretty good success early on and have been helped greatly by certificates and other information given to me by my uncle and aunts. One such certificate (the death certificate of my great-grandfather) lead me to an address in South Wales which I then visited to see if I could find out any more information about the Informant. I was surprised to find the person's daughter still living at the address and it turned out that she was my father's cousin (which neither he nor his brother and sisters knew about).
I will update my progress on a separate site here.
