My brother and newly found niece did. We found out that our deceased younger brother had a daughter he never knew he had. Nice young woman, about 35. She is married and has 3 kids, one of whom looks just like our brother when he was a young kid. We spent many hours helping her to fill in the blanks because she never knew who her biological father was. We sent her photos, a video, mementos, etc. She was so thankful for our help. Sad that both my brother and my deceased parents never knew about her.
