I have a profile whose existence was entirely due to the fact that she was raped by her step-father and took him to court. She was fifteen years old.
She has no birth registration, and had no known presence in online genealogies when I created the profile. Her date of birth is sourced from newspaper reporting of the rape trial.
I was looking for newspaper references to her mother at the time I found her.
If it were not for the rape trial, and my subsequent investigations into the birth of her daughter, her descendants would still be of the opinion that they are the the result of the rape. They would also not be aware of the half-family they now have.
She ended up abandoned by her mother and step-father, living in the street, incarcerated in the Destitute Asylum, having an illegitimate daughter to an itinerant plumber, leaving the country, getting married, and growing old surrounded by a new loving family.
I believe it important to document these events - they're in the record anyway.
Obviously the nearer to current generations you get, the more you need to treat them with respect.
I have one family I worked on in which I was told to stop by a descendent "because I'd get it wrong". The event in question (a fratricide) was 120 years ago. I asked them to tell the story in their words - which they had researched for decades - and they refused. Their research will end up in a shoebox in an attic, ultimately to be thrown away, and their family's story will be told by others anyway.
