For me it would be Joseph Jacobs, my GGGG grandfather https://www.wikitree.com/wiki/Jacobs-4497
He was born in 1820 in New York and died in 1864.
He is a brick wall and I don't know who his parents are. But the other reason is that he was Mortally wounded in the Hip on June 3rd 1864 at Cold Harbor, but he didn't die right way. It took him a whole week to die. He died on June 10, 1864.
I imagine him sometimes, lying in a hospital, in pain, dying, thinking of his family. At the time of his death he had four children and a 5th on the way. He'd never see them again and I'd be willing to bet he knew it. Besides the physical pain, I can only imagine the anguish he went through in those last 7 days.
After his death, the family suffered even more tragedy, His wife and youngest child would die within 2 years and the his 4 remaining children, scattered to the four winds. I still have no idea where 1 of them went.
Call me sentimental, but part of me would like to travel back those last 7 days and of course ask about his parents and siblings, but mainly to tell him, that he will live on in his memory and the lives of the family of his oldest daughter.
Here's a strange bit, before I depart. I visited the cemetery he was buried in some years ago. I found the section he was in and knew the grave number. I started to walk, looking at the graves, looking for his. His was the 3rd grave I looked at, 3rd row in, which in itself is not unusual, but the part which is odd is the fact that without realizing it, I had walked directly towards it.
