Reading this makes me feel that the deceased may have made contact in person with family or friends, and was rejected or made to feel he was unwanted or a shame to his family.
Maybe he had been living a lifestyle his family didn't approve of, and disowned him? Maybe it was something trivial but his family still held it against him? Maybe he disowned his family?
I know of 3 people that have no contact with either their parent or their child. In all 3 cases that I personally know, the reason is so trivial to me, but no talking or trying to rationalize with them has worked. None will budge in contacting the other feeling it's the other person's duty to contact them. It's foreign to me how you can live in the same area as a family member so close to you, but refuse to speak to them! In one case, a woman has one child, a son. She feels the son sided with her ex husband when they divorced and so for the last 20yrs, has not spoken to her only child! In the last year, she had a will drawn up specifically to write him out of any inheritance. Bizarre to me.
Another woman has 2 daughters. She left them as young teenagers within a month of their step daddy dying. She moved in with a man. That was a bit over 20yrs ago. She has limited contact with one daughter, none with the other daughter or grandchildren...
The third one I know of, a man in his 50s, his mother is dying with cancer. He is mad about her having an affair over 20yrs ago and leaving his Dad. So while he has had contact over the years, in the past year, he has become very angry and refuses to call and see how she is, or go see her, when she lives about 2 miles from him! His own mother...who is dying! And he knows his Mom has no contact with his sister and hasn't had any contact with her for 20yrs, again over the leaving their Dad.
Lastly I just remembered another one, a lady with an only child, a daughter, hadn't spoken to her or her grandkids for 5 or more years. But in this case, I understand the daughter's reasoning. The grandma remarried, and that man molested her child. Grandma sided with the man, and supported him during the trial and afterwards. In the last year, the Grandma has dementia, and the man has died. The daughter has tried to overcome, and have some relationship with her Mom, but with the dementia now, so many unanswered questions and lack of closure.
IMO, Lyle didn't want to be known for his reasons. Considering I don't see where he committed a crime, I am uncertain whether it's a benefit to identify him. That sounds weird after typing it. If he was found deceased, and it was a possibility of a crime having been committed, like he was killed, then I can see his identity needing to be known. While in theory, I would like to see all unidentified to have their name back, and would like to see family, friends, coworkers, neighbors, SOMEONE missing the person, and wondering what happened to them....maybe, just maybe it's not meant to be.
