1930 census yes I do believe that is Janie Janowitz and she was a widow but also it states her mother and father was born in NY , they were born in Austria.
The age was a sign of she didnt want Henry Presnell to know her true age even when he gave the info on her death certificate May 15 1935 he gave abt 1890 for her birth and her fathers name Abraham Striker, he did get the county right Austria, gave mothers name unknown
They couldnt have been married long. He was single in 1930 census in Honolulu. Janie must have met Henry in Honolulu
They are married in the 1934/35 city directory SF CA
