Where are they in 1920?

I've recently been going back over some of the data in my own families and trying to fill any holes in my research. I'm having a terrible time locating one of my paternal grandmother's sisters (and her family) in the 1920 census.  Let me try to paint a picture this branch of the family.

My grandmother's sister's maiden name was Lera Bell Fowlkes. According to the Virginia Phillips Fowlkes Howell family Bible, she was born 8 Sep 1888 in Monroe County, Mississippi. (I have a photocopy of this record in my possession. The original was last known to be in the hands of a cousin of mine residing in the Hatley area of Monroe County, Mississippi.) The 1890 census was destroyed in the infamous National Archives fire that so many of us wish had not occurred. She was too young to be listed in the surviving 1892 Enumeration of Educable Children in Mississippi which serves as an 1890 census substitute for many of us researching in that state. (It lists the head of household and school-age children, generally ages 6 to 16.)

In 1900, she is enumerated in the household with her mother and stepfather.

She married Neely Nash on 14 Dec 1908 in Monroe County, Mississippi. [Monroe County, Mississippi Marriages (1821-1921). 4 vols. s.l.: s.n., n.d., vol. 1, p. 175. This index is held at Evans Memorial Library in Aberdeen, Mississippi. If I have a copy of the actual marriage record from the county books in the circuit clerk's office, it is not in my database. I'll check some older paper files, but I'll need to make sure to obtain the better source for this. It's been added to my to-do list.]

At the time of the 1910 census, the family is still residing in Monroe County, Mississippi. They have a young daughter by that time. Evelyn Nesby Nash was born 17 Oct 1909 in Monroe County, Mississippi. There is a bit of a discrepancy in her one month age on the 1910 census and this October birth date.

Note about census: The enumerator made a mistake. He had originally tried to create a line on the same page below line 50 to include Nesby but had crossed this out and had made a note to direct the reader to the remainder of the household.]

I have not found the family in the 1920 census. They could have still been in Mississippi. They could have been in the process of moving to Arkansas. They could have been in Arkansas.

What I do know is that according to the 1930 census, daughter Edith was born about 1918-1919 in Mississippi and son Billie was born about 1922-1923 in Arkansas. [By the way, Billy was said to have been born in Mississippi in the 1940 census.]

You may have noticed that Lera is no longer in the 1930 census. She died in 1923, presumably in Arkansas, although it is possible that the family had made its way back to Mississippi. She is buried at Hatley Cemetery, Hatley, Monroe County, Mississippi. I have visited the grave which simply reads "Lera Bell Nash" and gives her birth date as 1888 and death date as 1923. This is also the reading that was rendered by a volunteer who transcribed the marker for Find-A-Grave (memorial number 66169047). There is one slight variation in the family. It's a more specific date, but it was possibly mistranscribed by a person who has been known to mistranscribe a lot of things. That date is 11 Jan 1928. I suspect that the actual date of death is 11 Jan 1923, and that this person wrote the 3 as an 8.

I'll include the 1940 census for the record.

The children of Lera and her husband Neely should be:

1. Evelyn Nesby Nash (b. 17 Oct 1909; d. 5 Mar 2000)
2. Emma Lee Nash (b. 17 Jun 1912) - name/date comes only from family information; probably died young
3. Ellie Hue Nash (b. 8 Jul 1914; d. 30 May 1970 )  - Tombstone gives birth year of 1913; SSDI gives 1914.
4. Josier "Joe" Nash (b. abt 1917)
5. Sada Odena Nash (Edith?, Eda?, Omie?) (b. 26 Jan 1920)
6. Billy Shaddon Nash (b. 31 Dec 1922; d. 29 Jun 1989)

I also have Neely's draft registrations for both World Wars, but I'm not including them here. I will say that Neely did say that he had a wife and three children on the World War I registration card in 1917 and that Omie is listed as the contact person on the World War II one in 1942.

So - where is this family in the 1920 census? I'm stumped. I'm beginning to think they were missed.
