The Short Answer
Joseph Smith’s relationship with Fanny Alger is one of the least documented and most disputed episodes in early plural marriage.
The Church describes it as an early plural marriage. Several later witnesses remembered a ceremony or sealing language. Other evidence, including Oliver Cowdery’s angry description, supports the view that the relationship caused a serious rupture and was not accepted by Emma.
The surviving sources are late, incomplete, and sometimes partisan. Calling it unquestionably an affair overstates the evidence. Pretending the episode is simple or well documented does the same.
Say This in Thirty Seconds
“Joseph had a relationship with Fanny Alger, and Emma opposed it. That should not be softened. Later witnesses described a marriage ceremony, while Oliver Cowdery used condemning language that critics read as evidence of an affair. Because the best details were recorded years later, the honest conclusion is that an early plural union is supported but the chronology, authorization, and sexual details remain uncertain.”
What We Can Say
- Fanny lived with the Smith household in Kirtland.
- A relationship with Joseph occurred before the better documented Nauvoo plural marriages.
- Emma reacted negatively.
- Oliver Cowdery condemned the relationship.
- Later accounts describe a ceremony involving Levi Hancock.
- No contemporary marriage record survives.
- There are no known children from the relationship.
Questions Worth Asking
- Which source is contemporary with the relationship?
- Does later testimony about a ceremony count as evidence, even if it is not conclusive?
- Does secrecy prove adultery, or can an unauthorized and secret plural marriage also explain it?
- Are we distinguishing “the evidence is troubling” from “only one interpretation is possible”?
Do Not Say
- “Nothing happened between Joseph and Fanny.” Something did.
- “We have a complete sealing record.” We do not.
- “Emma approved.” The evidence points the other way.
- “It was certainly only dynastic.” That is not established.
- “It was certainly adultery.” That is an interpretation of incomplete evidence.
Starting Sources
Why This Case Matters
Fanny Alger is often treated as the first and simplest test of Joseph Smith’s plural marriage.
If the relationship was ordinary adultery later relabeled as marriage, it cuts against Joseph’s moral and prophetic claims. If a ceremony occurred under a claimed commandment, the relationship belongs to the history of plural marriage, though that does not remove its ethical difficulty.
The problem is that almost every confident reconstruction outruns the surviving documents.
What Is Generally Agreed
Fanny was a young woman who lived and worked in the Smith household in Kirtland. Joseph had a relationship with her in the mid-1830s. Emma discovered or became aware of it and strongly objected. Fanny left the household and later married Solomon Custer.
The relationship contributed to conflict between Joseph and Oliver Cowdery. It predates the more extensive Nauvoo documentation for plural marriage.
That core is firmer than the details around it.
Evidence for a Marriage
Later witnesses connected with the Alger and Hancock families described a ceremony performed by Levi Hancock. Some accounts preserve language of covenant or marriage and remember Joseph teaching an early form of plural marriage.
These statements are relevant because they come from people positioned to know family memories. They are not contemporary certificates or journal entries. Most were recorded long after the event, when plural marriage was publicly known and defended.
Late evidence is not worthless. It is evidence whose memory, motive, and distance from the event must be weighed.
Oliver Cowdery’s Description
Oliver Cowdery referred to Joseph’s relationship with Fanny in severe language. A frequently quoted phrase from the documentary record describes a “dirty, nasty, filthy affair.”
The word “affair” is often read in its modern sexual sense. In nineteenth-century usage it could also mean an event, matter, or episode. The surrounding adjectives make Cowdery’s moral condemnation clear even if the noun alone does not settle whether he believed a ceremony occurred.
Cowdery was not a detached observer. He was a close associate in a painful conflict. His judgment matters, but it does not erase contrary testimony.
Emma’s Opposition
Any faithful treatment must leave room for Emma’s experience.
The available evidence does not show her calmly authorizing the relationship. Her distress and opposition are central facts. A claimed divine command does not make secrecy, trust, or consent unimportant.
Defending Joseph does not require treating Emma as an obstacle in somebody else’s spiritual story.
Was the Relationship Sexual?
The record does not give a reliable firsthand description of sexual relations. Many historians infer a sexual relationship from the nature of plural marriage, Emma’s reaction, and later testimony.
Other readers stress the lack of direct documentation and the uncertain shape of the earliest sealing practice.
There are no known children from Joseph and Fanny. That fact rules out a child claim. It does not prove abstinence.
The careful wording is simple: sexual relations are possible and often inferred, but the surviving evidence does not permit certainty about their extent.
Was This a Sealing?
The mature Nauvoo sealing system had not yet been fully introduced. Applying later categories to Kirtland can create false precision.
Some witnesses understood the relationship as a marriage under a revealed plural principle. Whether the ceremony had the same theological meaning as later eternal or time-only sealings is uncertain.
It is safer to speak of an alleged early plural marriage than to describe a fully developed Nauvoo sealing for which no record survives.
The Affair Argument
The critical case draws strength from:
- secrecy,
- Emma’s lack of consent,
- Cowdery’s condemnation,
- missing contemporary documentation,
- and the early date.
Those points make the affair interpretation plausible.
The limitation is that the case must discount or reinterpret later witnesses who remembered a ceremony. It also assumes that a secret religious marriage is merely a cover story rather than a category Joseph and his circle actually believed.
The Plural-Marriage Argument
The faithful case draws strength from:
- multiple later memories of a ceremony,
- family testimony,
- Joseph’s later documented plural-marriage practice,
- and early reports that he was teaching the principle in Kirtland.
Its limitation is the absence of a contemporary record and the risk that later public practice shaped memories of an earlier relationship.
Neither side gets certainty for free.
A Better Debate Standard
Ask three separate questions:
- Did Joseph and Fanny have a relationship? Yes.
- Is there evidence that participants understood it as a marriage? Yes, mostly later evidence.
- Does the evidence remove every ethical or historical concern? No.
This structure prevents the discussion from collapsing into slogans.
What a Believer Can Responsibly Say
A believer can hold that Joseph was attempting to obey a divine command while also believing that the implementation was painful, secretive, and marked by human failure.
A believer can also remain uncertain about this specific union without abandoning every later plural marriage as fraudulent.
Prophetic authority is not a demand to call every decision wise or every historical gap solved.
What a Critic Can Responsibly Say
A critic can argue that secrecy and Emma’s opposition make the affair reading more persuasive.
A critic should still acknowledge the later ceremony testimony rather than saying no marriage evidence exists. The strongest critical case uses the whole record, not only Cowdery’s most vivid phrase.
A Balanced Conclusion
The Fanny Alger episode is troubling because the evidence is thin where the ethical questions are sharpest. An early plural union has real historical support. So do Emma’s opposition, Cowdery’s condemnation, and uncertainty over authorization and sexual details.
The record does not justify a spotless devotional version. It also does not justify presenting ordinary adultery as a directly documented fact.
