Pergunta: Casou-se Joseph Smith com Fanny Alger como sua primeira esposa polígama em 1833?
There are no first-hand accounts of the relationship between Joseph Smith and Fanny Alger
One of the wives about whom we know relatively little is Fanny Alger, Joseph's first plural wife, whom he came to know in early 1833 when she stayed at the Smith home as a house-assistant of sorts to Emma (such work was common for young women at the time). There are no first-hand accounts of their relationship (from Joseph or Fanny), nor are there second-hand accounts (from Emma or Fanny's family). All that we do have is third hand accounts, most of them recorded many years after the events.
Unfortunately, this lack of reliable and extensive historical detail leaves much room for critics to claim that Joseph Smith had an affair with Fanny and then later invented plural marriage as way to justify his actions. The problem is we don't know the details of the relationship or exactly of what it consisted, and so are left to assume that Joseph acted honorably (as believers) or dishonorably (as critics).
There is some historical evidence that Joseph Smith knew as early as 1831 that plural marriage would be restored, so it is perfectly legitimate to argue that Joseph's relationship with Fanny Alger was such a case. Mosiah Hancock (a Mormon) reported a wedding ceremony; and apostate Mormons Ann Eliza Webb Young and her father Chauncery both referred to Fanny's relationship as a "sealing." Ann Eliza also reported that Fanny's family was very proud of Fanny's relationship with Joseph, which makes little sense if it was simply a tawdry affair. Those closest to them saw the marriage as exactly that—a marriage.
