Jöns Svensson - Jos Svensson

Jöns/James is my partners first cousin 4 times removed. All we had found is that he emigrated to the US.

I see you have a profile for him (record match after update). If you agree I suggest you go ahead and merge the profiles.

So you merged the two profiles into one. Good.

Jöns/James was your great grandfather then. This name "Jos", was that a nickname? If it was most people enter the nickname into the field named "Alias".

I see that there is other family trees that indicate that Jöns/James and his wife Johannah had five children, 2 girls and 3 boys, one of which was Jasper your grandfather. Does that match the information you have? Their names;

Johanna Elizabeth
Joseph Lawrence
John Samuel
Josephine Florence
Jasper Immanuel

Jons Svensson changed his name to James Swedberg. He chose Swedberg because it was similar to Swedenbourg. I was told he took that name because he admired Immanuel Swedenbourg. His son, Jasper was my grandfather. The names you list are correct
