My family has done all the DNA tests too. It's pretty fascinating. I found dnapainter.com last week and got addicted to it until I realized that people were too related - just when I thought a certain DNA segment belonged to a set of ancestors I found they belonged to another set. The problem is not a lot of people have family trees on the websites with the chromosome browser so I will probably wait for more advancements/matches to do more dna mapping, but I have been doing it a few years and learning a lot as I go.
What I thought was cool but probably disturbing to some was that the website I use to do some of the mapping, gedmatch.com, was used to discover the Golden state killer's identity. It usually only has around 200 people on there at a time so I thought that was very interesting.
There is a website,
https://www.relativefinder.org/#/main that will tell you your relationship to notable/historical people. I just went there and there is a group for just the Salem Witch Trials, there is a list of people and it will say whether or not they found a relationship to you. Out of the 79 people listed, none are my direct ancestors but I am related to 3:
Mary Walcott 1675-1719, 1st cousin 9x removed, accused people of witchcraft
Elizabeth Colson 1676-1725, 6th cousin 9 times removed, accused of witchcraft
William Stoughton 1631-1701, 1st cousin 13x removed, a magistrate in charge of the trials
I feel kind of bad that I appear to be a bit closer related to the accuser side..maybe one day I will find more relationships with the accused/innocent
There's also an app called "We're related". I'm related to thousands of famous people and so are millions. I think it is a good way to find out how each of us are related because it's the famous ones that tend to have more filled out trees.
