There were also Bastons other counties.

Based on the information for John Baston, I looked at the 1870 Census for an Eliza Morgan (she was, 'reportedly', married 40 years in 1910). Perhaps she married later in the year (after the Census was taken)?

Found the following possibility.
1870 Census, Texas, Anderson County - PO Box Palestine.

An Andrew Morgan (b. Va) and Lilla (b. AL) were listed with their seven children, including an "Eliza" (14), the second oldest and first to be born in Texas. IF this is the Eliza that married Marion, she would have been VERY young. Of course, ages varied by 5 years or more back then.
