Ooh, I have one. I was contacted by an acquaintance that heard I was good at finding people (through Ancestry website, and on line searches).
It appears that the government contacted her when her cousin died without a will. They assigned a government person to clear the estate / debts, final tax return and pay funeral expenses. They want her to locate the heirs / relatives to help with dispersal of the estate.
The problem is that there is one younger brother, who moved to the US from Canada around the age of 22 when their dad died in 1977. The mom also passed in 2003. The brother had not been heard from by any other family since he moved to the USA.
Given a not-too common name for someone we estimated as age 65, I think I found him. AND, I found evidence that the mom was one of 21 brothers and sisters. OMG. There are likely over 50 first cousins out there... just on the maternal side, plus more on the paternal side (I could only find evidence of the father, who I think was born in another country, but nothing on the father's family).
The estate has about $30k in it, she thinks, maybe more.
My friend is trying to get ahold of the person I found, although any listed numbers are now old and out of service. She has no intention of doing anything more than trying to find the brother to let him know his sister died and how to claim any funds. I suggested the next step was to send a letter to each of the last 3 known addresses, and be done with it. (It may not be him after all).
If she can't find the brother, she will just let the remaining $30k+ go to the government.
