This is how I found some relatives in the USA who also has moved back to Sweden
I am Carl Magnus Sälgö lower left. My son started in 2008 to get interested in our family tree and he sent a request to the Swedish Landsarkivet in Uppsala (was before I had Arkiv Digital)
My son sent a request 2008 to Landsarkivet regarding information about my mothers mother and got the answer A) below. My complement with links to Arkiv Digital in blue and transcriptions with yellow background.
After getting that information we succeeded to find Britta Sonja Linnéa Sjöstrand
As this was a part of the family tree we never had had any connections with I got some new story of how life was and why Britta left Sweden
So using Arkiv Digital, Google and Facebook was the key factors in finding now living people in the USA for me.
