Luke Tiernan Brien

Raised in Baltimore, he was educated at Georgetown (graduated 1846) and farmed in Baltimore County until 1854, when he bought a farm near Hagerstown. He served as volunteer aide to Brigadier General J.E.B. Stuart in 1861 and was at First Mananssas in July. He was commissioned Captain and Assistant Adjutant General (AAG) on the General's staff of on 24 September 1861, and appointed Lieutenant Colonel of the 1st Virginia Cavalry in April 1862.

He was in command of the Regiment on the Maryland Campaign.

He resigned his commission in the First Virginia on 30 September 1862, probably for reasons of health, and worked a plantation in North Carolina as overseer1. Apparently recovered, he took an appointment as Major and AAG on the staff of Major General W.H.F. Lee in April 1864, and served to the end of the War, being paroled at Appomattox in April 1865.

After the War he was a commission merchant in New York City, and general manager of the Illinois Central Railroad (1874-1882). He then bought farmland and mansion - formerly Landon House, Landon Military Academy, Shirley Female Academy - near Urbana, Maryland and resided there for the rest of his life.
