George Lucas was born in Dublin about 19 Feb 1750. He was convicted of pick-pocketing and shipped to Maryland as an indentured felon in Feb 1769, escaped from servitude, and enlisted in the Pennsylvania Line during the Revolutionary War. He fought in at least six battles and was wounded.
George joined several other sergeants in leading the Pennsylvania Line Mutiny of 1781. The revolt was resolved amicably, and George declined a reward for handing two British spies to American authorities.
He was arrested by federal troops in 1794 for participating in the Whiskey Rebellion and was imprisoned in Philadelphia for at least two months. He obtained bail with the help of his former commanding officer, faced trial for high treason, and was acquitted.

George died in Johnstown, Pa., survived by his only remaining child, David Lucas. He was predeceased by his wife, Lilly Ann (Dobson) Lucas and eight other children. He was buried at the Union Cemetery in Johnstown, which was destroyed by the Great Flood of 1889. His tombstone and remains were washed down the Conemaugh River, and a new marker was placed at Grandview Cemetery.*

—————————
George was promoted to Orderly Sergeant, just prior to the siege of Yorktown, during the Revolutionary War. He was present at the surrender of Lord Cornwallis. Originally interred in the old Union Graveyard, he was then finally transferred to the Union Plot at Grandview Cemetery. He died in 1844 at nearly the age of 100.*
