At about the same time as Longstreet began courting Garland, Grant became acquainted with and courted Longstreet's fourth cousin, Julia Dent, and that couple eventually married. Historians agree that Longstreet attended the Grant wedding on August 22, 1848 in St. Louis, but his role at the ceremony remains unclear. Grant biographers Jean Edward Smith and Ron Chernow state that Longstreet served as Grant's best man at the wedding. John Y. Simon, editor of Julia Grant's memoirs, concluded that Longstreet "may have been a groomsman", and Longstreet biographer Donald Brigman Sanger called the role of best man "uncertain" while noting that neither Grant nor Longstreet mentioned such a role in either of their memoirs.
