Many Swedes settled in Wisconsin in those years, as well as Illinois and Nebraska.I had been searching for Lydia Verlander's parents (the name on her death certificate) but I finally found her marriage license in Nebraska and her maiden name was Wallander, d/o Olof Wallander.Then I found their birth records in Kalmar Province, Sweden. Her brothers were Carl, Johnannes, Charles, Krestina and Charles O. Wallander.
I found another Swedish post that was from a Wallander/Wallender who claims his ancestors may have been a Verlander.
I belong to the Verlander Society of England (no, I am not British but a Texan), and their newsletter has lister the various changes in the original Femish-Dutch name "Van der Linde" or "Van der Lynde." The clan broke up pre-1571 from a place in West Flanders called Wervik. Other variations developed: Vander Lende/Linde/Lind, Vanderlender, Fardelender, Valender, Selender, Ferlender, Verlender, Falander, Valander, Vallinder, Wallander, Wallinder, Burland, Burlander, Berlander, etc.Many of the Verlanders settled in Colchester, England.
So, don't get discouraged. Use various spellings and also search Sweden. The LDS searcher produced several Wallanders and similar spellings.
