I have this mystery in the Smith Family History that I don't know the answer to, but perhaps someone knows the answer. See my comment on the 3 children in the 1910 census, who were not in the 1900 census.
162 Laura Elizabeth SHIRLEY (daughter of William H. SHIRLEY and Georgia Ann SMITH) b.21 Mar 1871, AL; d.31 Aug 1925, San Jacinto Co, TX; bur. Shepherd City Cem, Shepherd, San Jacinto Co, TX; m.16 Jul 1889, San Jacinto Co, TX James Madison “Matt” JEFFCOAT (son of Reubin JEFFCOAT and Selina Jane GARDNER) b.7 Oct 1871, AL; d.30 Oct 1951, Cleveland, Liberty Co, TX; bur. Shepherd City Cem, Shepherd, San Jacinto Co, TX. They had:
1621 Bertie Saline JEFFCOAT b.1 Sep 1890, TX; m. 1910 Elbert Enzer PATE; m. 1921 James Esmond STRICKLAND
1622 Maggie Elizabeth JEFFCOAT b.17 Dec 1891, Shepherd, San Jacinto Co, TX; m. William Finley COLE
1623 Rubin JEFFCOAT b. 1895, TX
1624 James JEFFCOAT b. 17 Nov 1896, San Jacinto Co, TX; m. Edna SHIRLEY
1625 Obie JEFFCOAT b.16 Mar 1899, TX; m. Paralea LOVETT
1623 Clemon Daniel JEFFCOAT b.16 Dec 1906, TX; m. Sarah Della McADAMS
1624 Jodie Payton JEFFCOAT b.15 Jun 1908, San Jacinto Co, TX; m. Ella CUTLER
Laura was enumerated in these censuses:
1880 Waverly, Walker Co, TX (in hh of her parents)
1900 Justice Precinct 4, San Jacinto Co, TX (with husband and 2 children)
1910 Justice Precinct 1, San Jacinto Co, TX (with husband and 5 children)
1920 Justice Precinct 2, San Jacinto Co, TX (with husband and 2 children)
In the 1900 census Matt and Laura JEFFCOAT only had two children. The census also indicates that she had only two children with two living. In the 1910 census Bertie and Maggie had already married, but Matt and Laura had five children and three of them (Rubin, James and Obie) were born before 1900. I have found no record of them in the 1900 census. Possibly they were adopted, but there is no indication of any adoption.
James JEFFCOAT’s wife, Edna SHIRLEY, was the daughter of William Pinkney SHIRELY and Dora HUTCHENS. William Pinkney SHIRLEY was born in Mississippi in 1870 and moved with his family to Texas in 1874. It is unknown how or if this Shirley family is connected to the Shirley family from Henry Co, AL.
