Headstones in cemeteries and the GDPR regulations

[zetlander]

agree with Tin Man - don't recall ever seeing names of relatives of the deceased on a headstone -  plenty with references to the deceased being
 '....... dear husband/wife  mother/father grandfather/grandmother' etc -
 but no names of living relatives at the time of death on the headstone.

I have sometimes seen these gravestones with the names of living people, particularly children, listed on them.
I photograph gravestones for findagrave and when I make a memorial for one like this, I add the photo but I don't type out the inscription naming the living children. Findagrave instructs us not to name possibly living people in the memorials we create.

There is enough information online to identify people, especially if they have anything unusual about their names. It's not long ago that I shocked fellow trustees of a charity I was a trustee for, by handing two of them (both married and female) a piece of paper which their mother's maiden name and at least one past address was written on. All I had needed was their everyday names and a good idea where they lived.

Any competent genealogist in the UK can fill in the boxes on Ancestry marked "private", unless there's a common surname involved. For that reason neither my daughter nor her children are included in my tree, which is also private.
