From Patronymics in Sweden https://www.wikitree.com/wiki/Space:Patronymics_in_Sweden
these are the directions. When a patronymic was used in combination with an established family name, use the family name as Last Name at Birth and put the patronymic in the Middle Name field. This will display right in most contexts. Using Patronymic_FamilyName prevents the profile from showing up in the indexed family name listing and obstructs searches.
My grandfather was born Joel Nilsson and changed his name to Joel Nils Sandberg after coming to the United States in 1883 at the age of 20. The above leads me to think that I should use Sandberg as the “last name at birth”. I have used Nils as his middle name and Nilsson in Other Last Names, which is different than these directions. His name reads “Joel Nils Sandberg (1863- abt.1938)” in the heading and “Joel Nils Sandberg aka Nilsson“ at the top of the profile.
It will remain necessary to have the last name of Nilsson for further searches of Swedish records and the last name of Sandberg for further searches of US records, so to my less experienced WikiTree eye, the solution seems to use the “other last name” field. My question: is there any reason why this shouldn’t be used?
A second example- I have not yet made a profile for Joel’s wife as I want to be sure I’m on the right track.
His wife was Sara Angelika Nilsdotter at birth, became Sara Angelika Nelson upon arrival in the US, and Sara Angelika Sandberg after her marriage. (They were no relation and, in fact, came from completely different parts of Sweden, but both had fathers named Nils.
Sara Angelika is a “double name” - another Swedish naming convention that is strange to English speakers. Again from Given Names in Sweden https://www.wikitree.com/wiki/Space:Given_names_in_Sweden
these are the instructions.
If we follow the way people used these double names, both names should be entered in the First Name field, and the radio button for No Middle Name should be checked. We just have to put up with the validation blurb from the system, and click SAVE ANYWAY.
First Name: Sara Angelika
Middle Name: no middle name
Last Name at birth: Nelson
Other Last Name: Nilsdotter
Would read “Sara Angelika Nelson (1873-1940)” in the heading and “Sara Angelika Nelson aka Nilsdotter“ at the top of the profile.
