"Harry," a person in my file, was raised by his legal parents, but after their death he learned that his actual father was a long-time friend of the family (also deceased) who had been known to him as "Uncle Bob" (not his real name). Uncle Bob had never publicly acknowledged the relationship during his life, although it was known to close family members.

I am at a loss how to treat this situation in my family file. Harry (now deceased also) was raised by his legal parents, but has a blood relation only to his mother. His legal status is in conflict with his genealogical status.

Should I enter a duplicate card for both sets of parents, and show him as an adopted son of his legal father? There are many descendants, and some of them have mixed feelings about making the situation public, so I intend to remove Harry's personal information from the file that is uploaded to the internet, but I don't wish to falsify the paternity.
