I know of a living person born around 1950 with a 4th cousin 3x removed born in 1859 and their shared ancestor was born in 1668. So even though they are separated by 100 years, they are still considered close cousins.

A living person being a cousin of the Mad Trapper, born c. 1900, would not be much different. For a shared ancestor to be born in 1776, they would most likely have to be close cousins maybe 2-3x removed. If they are distant, the shared ancestor is further back.

Good point. If you want to help identify him, best bet is to you add your autosomal DNA profile to a genealogical database that works with law enforcement search.
At this point, assuming Gustaf Magnusson’s and Britta Svensdotter’s descendants are on AncestryDNA, anyone who thinks they’re related to the Mad Trapper can join AncestryDNA and see if any of the descendants come up as cousin matches. You just have to search all the familial matches’ Family Trees for pedigree names like Magnussen or by location like Kulltorp. You wouldn’t even need complete and linked Family Trees.

There’s a very strong person of interest but we’re having trouble getting a conclusive DNA match. Working on one more relative.
 
Police in Calgary, Canada assisted in tracking down the identity of a victim of serial killer Keith Jesperson.

The victim had recent Norwegian DNA that led to possible relatives in Canada.

“This case was exceptionally challenging due to recent Norwegian ancestry which resulted in very distant DNA matches on GEDmatch and FamilyTreeDNA,” DNA Doe Project team leader Cairenn Binder said in a statement.

The organization said Catalano made the most of the information discovered through genealogy by contacting potential family members and encouraging them to voluntarily upload their DNA profiles to GEDmatch, a public DNA database that can be used for forensic cases.


 
One of the mentioned possible identities of "Albert Johnson" is Arthur Nelson.

Arthur Nelson was a lone trapper and reclusive individual who was believed to be part Swedish, or at least of Scandananian ancestry. He trapped in the Canadian Yukon area from the mid to late 1920's, often living on the outskirts of settlements. He traveled without dogs and was known to carry a Savage model 99 lever action rifle.

He was also suspected of committing a series of unsolved murders. Among them:

Charles Taylor (aka Yukon Fisher) was murdered in 1927 and his cabin burned near Fall River.

On 5 October 1928, three persons went missing. Elizabeth Ray, wood cutter John Timson, and Dr. J. O. Chappelle were traveling in Chapplle's canoe from Stewart Island to Dawson City on the Yukon River, a distance of 75 miles. Their bodies were never found, nor was a quantity of jewelry reportedly carried by Ms. Ray. The Canoe was located, shot through with a bullet. The Doctor's cocker spaniel was also found alive.

In May 1929, Angus Hall, James Gilroy, and Andrew Hay all disappeared in the South Nahanni River area.

In 1932, the body of Phil Powers was found in a burnt out cabin near Fall River. His head had been crushed.

While mostly circumstantial evidence such as rudimentary identification and Nelson's presence in the area of these cases at the times point to him as a serial killer, the finding of gold teeth and bridge work in the possession of "Albert Johnson" strengthens the possibility that Nelson and Johnson were one and the same.

If "Johnson" was in fact a serial killer, it would certainly explain his shoot outs with and flight from the Mounties.

Nelson carried the same type of rifle found with Johnson's body, and he seems to have disappeared at the same time of Johnson's death.

Although Arthur Nelson might have been Albert Johnson, could both names have been aliases?
 
If "Albert Johnson" had served un the US Army during World War One (1917-1919 time frame) he would probably be listed in the Adjutant General records of Washington state.

Those records, which can be searched on line, contain rosters and abbreviated service records of many who served in the National Guard and National Army.

Unfortunately, there are over a dozen Albert Johnsons and a dozen Arthur Nelson's listed. And both names could have been simply aliases used by the "Mad Trapper".

However, this resource might be of interest in looking up other possiblities.
