Thank you for replying. Yes, in 1900 he does appear to still be in Wisconsin, however, that same year or possibly early 1901, or so family story has it, they are living in California (San Francisco area), and records do have them by 1910, living in Oregon, without William. In 1905, Anna is married to an Alden, though official record has not been found it is accepted family history, and she even has a daughter by Alden, (we believe Charles Alden). So, between 1900 and 1910, we"officially" loose track of them.
There are so many William Beans with similar birth dates and locations it has been a nightmare trying to figure out which one is mine.
Your help is greatly appreciated.
