Another census puzzler

I've been browsing the 1940 census and finally found this family - but look how tricky they made it!

This is the family in 1930:

Here they are in 1940:

Whoopsadaisy!

Nancy Missouri Slinker

This is all I have had on Nancy Missouri Slinker for some time:

County of Metcalfe, State of Kentucky,
Page No. 58/[866],
22 June 1860 by Dory Nell,
P.O. Eastfork
[near John (son of Frederick and Susannah) and Mary Grimes Slinker],
line 7, 381/381 Missouri SLINKER 41 F House Keeper Ky,
Narsette 19 F do [Ky],
John N. 17 M Day Laborer do [Ky]
Joseph 15 M do [Ky]
Susannah 13 F do [Ky]
Kindrick 10 M do [Ky]
Alonzo D 7 M do [Ky]
Samuel D 2 M do [Ky]

Then I found this:

Kentucky Death Records, 1852-1953, ancestry.com
Name: Narsetta Green Jewell
Death Date: 29 Dec 1914
Death Location: Muhlenberg
Residence Location: Muhlenberg
Age: 75
Gender: Female
Ethnicity: White
Birth Date: 14 Mar 1839
Birth Location: Hart, Kentucky
Mother's Name: Nancy Misoura Slinker
Mother's Birth Location: Hart, Kentucky 

I found someone online who said that Missouri's son Samuel D. Slinker [later Sinclair] had parents noted on his death certificate as "Kixon Sin Clair" and "Nancy M. Smith".

So the question is, who was right?

I believe the answer is a qualified yes...

I found this record:

Kentucky Births and Christenings, 1839-1960
noted 13 Feb 2012
familysearch.org
name: Lewis V. Smith
gender: Male
birth date: 21 Mar 1858
birthplace: Barren, Kentucky
father's name: Thomas D. Smith
mother's name: Missouria Slinker
indexing project (batch) number: C01993-6
system origin: Kentucky-EASy
source film number: 216816

I believe it is actually Samuel D. Slinker/Sinclair's birth record.

And it would make his parents not Kixon Sinclair and Nancy M. Smith, but Thomas Dixon Smith and Nancy Missouri Slinker.

These are close enough that I am comfortable making the leap in logic.

If I found that Samuel's birthdate was near 21 Mar 1858, I would be entirely convinced.

I am now adding Missouri as one of Lewis Slinker and Cenia Slinker Slinkers's missing daughters, but only because no one else appears to be missing a daughter in the right age range.
