Family Trees in Cyberspace
Caution is generally advised to all who enter their precious family tree data on the internet in general.
I have seen all too many details on the living at the various gene sites such as genesreunited, gencircles, rootsweb world connect family tree projects, just to name a few. These details have included full dates of birth, marriage info etc.
Most family tree sites have a little disclaimer requesting users to ask permission of their living relatives before they enter their data, but I'm sure this is not always the case.
It would be all to easy for one unscrupulous person to use data on the living to another's disadvantage.
A simple rule of thumb is the '100 Year Rule' ... let's say someone was born in 1906 we must assume that in the year 2006 they are/or could be still living. So, it's basically a good idea to either have them as 'LIVING Smith' and an appoximate year of birth if an entry is compulsory ... say, 'abt 1923'.
And everybody please remember to record your sources of data, even if it came from another genealogist. Otherwise you may kick yourself later on as we don't really have memory banks like computers.
