I have seen the marriage record for "James Akers" marrying Sarah Angle in 1840.But not for "James B. Akers". This would not account for Henry S. Akers born 1832 and he is certainly the son of James B. as indicated later in the Indiana census reports from 1870 ( James B. and Selina appear) and 1880. Nancy Sue died before 1832 when her father's will was written.Yet as I mentioned, two additional children are born before 1840.The one in addition to Henry is Edith Akers, b. 1830.I found her death date in a later chancery case and have sent for an official death certificate - will let you know if one exists or has good information. I tend to think that Sarah Angle married one of the many other James Akers in Franklin County.
