If her husband was Alex, this might be the family in 1910:

1910 United States Federal Census
Name: Bell Loggins
Age in 1910: 30
Estimated birth year: abt 1880
Birthplace: Alabama
Relation to Head of House: Wife

Spouse's name: Alex

Gender: Female
Household Members: Name Age
Alex Loggins 35 abt 1875 AL
Bell Loggins 30
Sara Loggins 14 abt 1896 MS
Jerry Loggins 12 abt 1898 MS

On the image they are enumerated as a separate household, living in the same dwelling (#919) with a widowed Edith Nally, 48, born in MS. And another widow, 55, Martha Love, and her 20 y/o son, Frank Burton.

The census reflects both Alex and Bell reported this as a first marriage for them, and Bell reported she was the mother of 4 children but only 2 living.

Have you ordered a copy of her original application for a SocSec #? She would have been required to list her parents' names including her mother's maiden name. This could be her SSDI listing:

Linda Durr-Rudd could probably obtain a copy of Alex and Bell's marriage certificate (email rtnlinda@earthlink.net) and her website is http://www.angelfire.com/folk/gljmr/index.html. Sometimes witness names on the marriage certificate can provide helpful info:
