DNA parent relationship type
I've just helped a person identify her biological father via DNA. I didn't find any satisfactory way to show that she was 52 before she knew who her father was.
I suggest a new relationship type for the parents that reflects this kind of relationship. I might suggest "DNA" or maybe "Brief" or something similar. You decide. But something is desperately NEEDED.
In addition, please add a new marriage event that says "Never married" or something similar.
My temporary solution is that the person has a mother with no father. Then I added the father as a new parent with no spouse. It is awkward, but least confusing.
It also means that the person has 2 half pedigree charts. I'd prefer one
This is a VERY common situation (this is not the first time I've dealt with this) and should be handled up-front and not ignored and obscured! This is, after all, the 21st century.
