Trivia 5-1-17 does it "motto"?

[Brenal]

Faugh A Ballagh was the battle cry of the Army of the Potomac's Irish Brigade – composed of the 69th New York Volunteer Infantry, the 63rd & 88th New York and later the 116th Pennsylvania and 28th Massachusetts Infantry regiment. It was specifically the motto of the 28th Massachusetts.

It was popularized outside Ireland during the American Civil War by the Army of the Potomac's Irish Brigade – composed of the 69th New York Volunteer Infantry (NYVI) or "Fighting 69th", the 63rd & 88th NYVI, and later the 116th Pennsylvania and 28th Massachusetts Infantry regiments.

63rd New York Infantry, 69th New York Infantry, 88th New York Infantry, 28th Massachusetts Infantry, 116th Pennsylvania Infantry...collectively known as the Irish Brigade.

Edit - I can verify that the 69th New York and 28th Massachusetts used this as their regimental motto, but I can't verify the other three.

Wiki sez:
It was popularized outside Ireland during the American Civil War by the Army of the Potomac's Irish Brigade – composed of the 69th New York Volunteer Infantry (NYVI) or "Fighting 69th", the 63rd & 88th NYVI, and later the 116th Pennsylvania and 28th Massachusetts Infantry regiments. A variant transliteration of the motto, 'Faj an Bealac!' was inscribed on the regimental colors of the (Federal) 7th Missouri Volunteer Infantry, the "Irish Seventh", which fought in the Civil War's Western Theater as part of Grant and Sherman's Army of the Tennessee.

It looks like most (if not all) regiments of the Irish Brigade used "faugh a ballagh" as a battle cry, I'm leaning towards the 28th Massachusetts as using this as their motto.

If we can believe wikipedia ("Faugh a Ballaugh"), it was used by the several regiments in the Irish Brigade:
"It was popularized outside Ireland during the American Civil War by the Army of the Potomac's Irish Brigade – composed of the 69th New York Volunteer Infantry (NYVI) or "Fighting 69th", the 63rd & 88th NYVI, and later the 116th Pennsylvania and 28th Massachusetts Infantry regiments. A variant transliteration of the motto, 'Faj an Bealac!' was inscribed on the regimental colors of the (Federal) 7th Missouri Volunteer Infantry, the "Irish Seventh", which fought in the Civil War's Western Theater as part of Grant and Sherman's Army of the Tennessee."

https://irishamericancivilwar.com/2012/01/07/faugh-a-ballagh-the-17th-wisconsin-at-corinth/ describes the 17th Wisconsin using this motto at Corinth in October 1862. It appears that it was popular with all regiments consisting of mostly Irish immigrants, including those fighting for the Confederacy http://northcarolina.universitypres...5149/9781469607573_Gleeson/upso-9781469607566.

Edit - I am also accepting the 69th New York and 7th Missouri as correct answers.

A number of other regiments were suggested, but I could not verify that "Faugh a Ballagh" was the regimental motto of any of them. I could verify, in some cases, that it was their brigade motto, but not that it was their regimental motto.
