Mr. White,

Below is a link to a capsule history of the Eleventh Tennessee Cavalry Regiment (CS) from "Tennesseans in the Civil War, Part 1".

Below is a potential clue for you if this is your ancestor and ancestor's widow. This lady filed for a Tennessee Indigent Widow's Pension in the post-years.

NAME: White, Benjamin Franklin.
WIDOW: White, Mary Josephine
PENSION #: W1510
COUNTY: Marshall

You can obtain his Compiled Military Service Record through this web site from the link at the top of the page.

He did not file for residence in the Tennessee Confederate Soldier's Home or file a Tennessee Civil War Veterans' Questionnaire.

I hope this helps.

Respectfully,

Gerald D. Hodge, Jr.

Historian: 39th Georgia Volunteer Infantry Regiment
