Man, just leave a note. If you have numbers for next of kin, why wouldn't you put it in a note? If you don't want to leave a "spill-your-guts-type-note", just jot down next of kin and contact numbers or addresses on a piece of paper. I don't understand the big deal here, really. I guess they could take your DNA and compare it to DNA on a genealogy website and track down some relative of yours that way. I suppose the police could canvass your neighbors and seek clues about your relatives like that. and you can just search a person's name on Google and have pop-up scores of sites that have some info about the searched person along with likely family members and other connections. We have all made trails in our lives. With all that said, though, there are instances whereby some people are extremely under the radar and can be much harder, or impossible, to identify. It can happen. But, it sounds like your'e really not in that group. Just tell them who to contact, whether a family member, really distant family member, coworker, priest, whoever. In the plan I'm working on now, since I am so alone, because all of my family has passed within the last few years, and because I KNOW that when I go it will LITERALLY be weeks and weeks before anyone even finds me, I cam up with the idea that on the day I decide to go, I am going to send a short note to my local police headquarters explaining what I have done, where I live, and any other pertinent information they might need to know, such as precautions to take, etc. I, guess, eventually, the police would be called once my mail starts piling up in my mailbox. I think the letter carriers still do that. But, I don't get that much mail and that might take a while to happen. And I know that it really doesn't matter how long it takes to find me once I'm gone. For some reason i just don't want to be lying there for weeks on end, possibly with animals feeding off my carcass. I'm going to have as many of my affairs in order as I possibly can. But, I have a limit on how long I'm willing and able to hold off. I know I won't have everything in order as I would like and I'll be leaving some type of "mess" that someone else is going to have to deal with, since I have no family to take care of my estate once I'm gone. The court will have to appoint a "professional taker care-of" person to deal with my shit.
