Additionally Joan Whitaker is posing an important question. Very.
To which I add -- when is the information available actually private when at www.familysearch.com, www.rootsweb.ancestry.com, www.findagrave.com, and through search engines such as www.google.com there it is, open, public, up front, visible ...
What information is specifically private? How do we KNOW this is private when we find it laid out on the www -- not just in the parentless profile? What is it I'm supposed to be protecting? There they are in the profile, probably alive, and there they are in bits and pieces "all over www". Now what?
And what about all the PM who have entered like data on their own people? Have they violated someone's privacy if that privacy is in tatters across the www? Are they in effect saying "I'm not going to let you see this information even if it IS splattered across www."?
I still think being ruthless that one should not enter the profile of anyone you know is alive; that before you enter anyone, check online with the search engines and databases widely available to us, to see if you can locate a death record; and if you have any doubt, then don't enter even their name.
Come to the obit, use the famous ellipsis ( ... ) as in "survived by son... and sister .... and grandchild ...."
If you want provide the URL for this in the Sources that's okay.
BUT it is a bit a toe-crusher when whomever has posted the memorial at Find A Grave has ALREADY PUBLISHED THE NAMES OF ALL THE SURVIVORS along with it ... NOW it is public, NOW it is no longer PRIVATE, yes? So you don't need the ellipsis ( ... )
So what is it we are to protect?
It's on the web. It's in databases. It can be found by a fee to a company which will do all the searching. It can be found in obituaries, announcements, etc and so forth and those can be had by access also I was told, some web site that lets you read newspapers in a search for someone ... if they're in the database of newspapers you can see it ... forget whether it is free or by subscription ...
