Was just looking at the 1830 census and it shows a strong possibility that Lucinda McElyea who married Bennett Wright may be connected to the wrong set of parents.Here's my reasoning -
Jesse McElyea (son of Hugh McElyea) was living in 1830 Jackson Co AL.In his household, besides his 2nd wife Elizabeth, there are 4 children - 2 males (one under 5 and one between 5 and 10) and 2 females (both under 5).
If Lucinda's birth info which shows a birth year of 1821 is correct, then the 1830 census does not include her and thus puts a shadow on her connection to Jesse.
Possible answers from the 1830 are that she may have lied about her age by adding a few years or she is not Jesse's daughter but belongs to another McElyea family or she was not a McElyea whatsoever.
Lucinda's ancestral line needs to be thoroughly researched to see where she fits into the McElyea family if she really belongs to it.
