Mary Louisa Swan Clapp

I received a comment from "jsl" which pointed out the following:

W. T. Hearne on page 791 states:

"Mary Louise Hearne, daughter of Francis Sharpe Hearne, Sr., married a Mr. Swan, and they had one daughter, Louisa, who married a Mr. Clapp, and moved to Texas. "

Could the following census entry refer to Louisa and husband Clapp?

1900 census, Hood County, Texas, Justice Precinct 6, ED #93, Dwelling #68, Family #68
CLAPP, William Head WM Dec 1847 52 M32 TX/IL/TN farmer
CLAPP, Luisa S. wife WF Dec 1849 50 M32-9-7 GA/GA/GA
CLAPP, Grace Daughter WF Jan 1882 18 S TX/TX/GA
CLAPP, Allen B. Son WM Nov 1884 15 S TX/TX/GA
CLAPP, Annie L. Daughter Sep 1887 12 S TX/TX/GA
CLAPP, Ben E. Son WM May 1891 9 S TX/TX/GA

I agree with this. Looking at the information, there is more circumstantial evidence that boosts this conclusion.

First, the suggestion already has a lot going for it because of the approximate age of Louisa, and the Georgia birth. Here is some additional information.

There is no family Swan in Georgia with a child Louisa. However, our Mary Louisa Swan, age 10, is living with her aunt and uncle, Sarah Hearne and Jos. Freeman, Indian Springs, Butts, Georgia in 1860. This must be our Swan, else why a Swan living with the Freemans? So Mary Louisa's parents appear to have died.

Mary Louisa is not living with the Freemans in 1870. She would have been 20, based on the 1860 census. Hearne says she married a Clapp and moved to Texas. There is a Lu Clapp married to William Clapp, age 20, born in Georgia in 1870, in 4th Precinct. Houston County, Alabama PO. They have one daughter.

Family 206
William Clapp, 32, M, W, TX
Lu Clapp, 20, F, W, GA
Bettie Clapp, 2, F, W, Texas
David Smith, 23, M, W, Virginia, Farmer

William is not with his family in the 1880 census. But it is the same William with birth, father birth, and mother birth the same:
