Here are the profiles Markus Borg is currently working on. Can you help?
The 12y orphan in a barn https://www.wikitree.com/wiki/J%C3%B6nsdotter-4222
What was my great-great-grandmother Gustafwa Jörnsdotter's life like? With whom did she have Martin? Did she really "sell" Martin to the lowest bidding local farmer at the age of 12? Did Martin have to sleep among animals in a barn? When and where was she recorded dead?
The first Borg https://www.wikitree.com/wiki/Magnusson-1027
When did my great-great-grandfather Anders Johan take the name Borg? Why was he known as Andersson before that despite having a recorded father called Magnus Ericsson?
The DNA matches
A number of potential third cousins have been identified through 23andMe, e.g., in the US. Who is the link? Who emigrated?
