Long shots are always worth taking.Given the 19th century phonetic spellings and manner of enumeration prior to 1850, it is really difficult to sort out these individuals from on-line sources.
William Likin's daughter Rebecca was born ca. 1797, married John Ryland in 1819,Washington County, TN, where they lived for the rest of their lives.She and her husband are buried in the OLD JONESBORO CEMETERY, Washington County TN, In section H, row 4, no. 2: John Ryland, b.1795- d.1857; Rebecca Livens Ryland b.1797 - d.1866.
A Likins descendant, Alberta Haas, provided the information about Rebecca Likins.I think, but am not positive, that it came out of a family bible.So assuming the identification is correct.William Likin's daughter Rebecca was married and living with her husband, John Ryland, around Jonesboro, Washington County, at the time your Rebecca married James Cannon and when the 1830 census was taken.
FYI, a "Lacking/Lakens" family does appear in various early 19th century census enumerations, can't remember the first name of the household head but you might want to check that indivual out.
