Four Lewis men and Two Lucy/Leticias - HELP!

This is what I'm coming up with--is it true?
HARLAN CO KY - FOUR LEWIS MEN with TWO LUCY/LETITIAS?
and...did my great-grandfather's mother become his first cousin once removed?!!

John Lewis Sr. and 2nd wife Elizabeth Morgan had son HIRAM, born 1831.

1. HIRAM and LUTISHA ELY
they may have had other children besides:
an infant son John G. or B. born Oct. 1853 and died Jan. 1854.
son Jonathan born May 7, 1855

2. ABNER LEWIS MARRIED LETITIA LEWIS
1860 census: Abner 22 and Letita 25 live in his
father Eli Lewis household with no children of hers.
1860: Jonathan, 5, and Catherine, 8, live with
John Lewis Sr. and Elizabeth. THEY WOULD
BE THE CHILDREN'S GRANDPARENTS--HIRAM WAS
THEIR FATHER and JOHN SR'S SON.
and...

3. JAMES Lewis and LUTESAH Smith had son Daniel Aug. 5,
1854, Harlan. I have not found a marriage for these two
Who are her parents?
1860 a James Lewis and an 18-year-old LUCY SMITH
and SIX YEAR OLD DANIEL live in LETCHER CO KY.
A James Lewis, according to a local story, died
in Letcher Co in the Harlon Co
Battalion,which was active
Oct 1862-Jan 1863. (This agrees with family lore)

4. JOHN LEWIS married LUCY SMITH Jan. 25, 1863 at ELY
LEWIS's house. Is this the same Lucy who was with
James? Is she little Daniel's mother?

1870, Daniel lived with his grandparents (a pattern
here!) Hiram and Lucinda Jenkins Lewis.

Is this John Lewis the son of Abner Lewis Jr and a nephew of Eli Lewis? John, 20,
lived in his father's house in 1860.

DOES ANYONE KNOW the Lucy Smith who married John Lewis in
1863? or the Lucy who had Daniel in 1854?
Does anyone know where John and Lucy Lewis are in 1870?

The four grooms are, of course, related: Abner, James, and John are first cousins, grandsons of Abner and Eleanor
Lewis. Hiram, Lutitia's first husband, is the son of John Sr. their grandfather's brother--so he's one generation older than they.

Poor little Daniel Lewis was my great-grandfather. I've worked to find his mother and I wonder if she became his
cousin!!!

Any help, ruling out or confirming, would be much appreciated.
