I've found some information about Adolph and am attaching some items of interest. Unfortunately, Alberta puts no records online so it limits searching.
The Tauber family is listed as Lutheran on all documents. No evidence of them being Jewish and did not find anyone Jewish marrying into the family.
Adolph Carl Tauber was born 16 September 1885. He gave Sedlez as his place of birth but there is no such place. The person taking the information probably spelled it phonetically. The closest I could come to it was Siedlce, which is pronounce sort of like Sedlez. and is only about 30 miles from Węgrów, Poland where some of his siblings were born. His parents were Johann TAUBER and Maria OHLKE to whom a total of 14 children were born, though all did not survive. The family arrived at Ellis Island in 1908 and made their way Alberta where they lived at Cooking Lake.
Adolph married Olga DIEWERT around 1914 in Alberta. Olga was born 14 March 1894 in Volhynia, Russia. They had two children: Herman James Tauber born about 1915 and Wanda Tauber born about 1918.
Something happened to Olga and in the 1921 Canadian Census she is a patient in the Provincial Mental Hospital in Ponoka, Alberta. I cannot find confirmation but it looks like she died there.
One of Adolph's sisters, Adella, married Edward Diewert, brother of Olga. Adella died 14 November 1981 in Kelowna, BC.
In July 1920, the two children, Herman and Wanda, entered the US at Eastport, Idaho with their Aunt Hilda (another of Adolph's sisters) and their aunt Adella, her husband Edward Diewert and their five children. They were going to Dallas, Oregon where some Diewerts already lived. The two children's passage was paid by Adolph but it doesn't indicate where he was. They listed their closest relative in Canada as their mother, Olga, in Ponoka.
In the 1930 US census, Adolph, Herman and Wanda are living on a farm on the Westside Highway in Whiteson, Oregon.
On 4 July 1933, Herman James Tauber was killed in a car crash.
In April 1942 Adolph completed his WWII "Old Man's Draft" registration. He gave his address as Route 1, Amity, Yamhill and his contact person as Miss Wanda Tauber, 117 3rd Street, Corvallis.
Adolph was naturalized an American citizen in 1946 in Oregon, case #443.
I've found some newspaper articles in the Oregon Statesman about a Wanda Tauber that is the right age and living in the right places. The first is in 1954 when she'd been in some trouble with the law. The second are ads during 1962 offering housework services. The last is 1964 when she was in a car accident and hospitalized with a broken leg.
On 15 April 1966 Adolph married Sylvia Kerr Darbison. He was 80 and she was 78. He died three years later on 25 November 1969 in McMinnville.
Hope that information helps.
