Terve!
The wife of Adolf Ferdinand did not die in Firshaga in the 20ies. She emigrated together with her son Ferdinand to USA after her brother's dearh 1926. She died in Ohio 1937. Her son took his mother's maiden name Fielding in USA. So look for Fred(F reddy) Fielding in american files. I have somr facts about the fielding familiy in Rus sia and Finland and of corse in Sweden and Norway if you're interested.
Kindest regards Vänliga hälsningar
