Research would seem to indicate that the first Yanceys were baptized into the LDS faith as result of the preaching of Levi Stewart in 1844 in Illinois.

Oct 1843-April 1844 Levi Stewart writes a letter to the Times & Season, Nauvoo, Illinois, dated 13 April 1844. “I have traveled near six months since July last, most of which time I labored in Franklin, Williamson, and Johnson counties, in the south part of this state, Illinois. There had been but few discourses delivered by any of the elders in these parts, therefore, prejudice was great. After hearing the Gospel for themselves, the honest in heart began to discover the many falsehoods that have over ‑run the country, and began to investigate the doctrines of Christ. The result was, many believed, and I had more calls for preaching than I could attend to, and through the assistance of God, I was enabled to baptize 24 souls. I left many more believing; whom I hope will obey the Gospel. There is a great door open for preaching. My prayer to God is for the rolling forth of His Kingdom, Until the kingdoms of this world become the Kingdoms of our God.” Your brother in the Everlasting Covenant, Levi Stewart

The exact details of the Yanceys conversion is not known - but among those that converted were probably: Hiram Yancey and wife Elizabeth, William Riley & wife Elizabeth, Matilda Yancey, Thomas Yancey, Benjamin Kelly & wife Nancy Yancey, Joseph Smith & wife Mahala Yancey, James Duncan
