||Obit., New Orleans Item, 27 Aug. 1920:|
Funeral of Col. McLellan Is Held at 10 a.m. Friday
The funeral of Col. Alden McLellan, Confederate veteran and prominent financier of New Orleans, who died Tuesday night as the result of injuries received when struck by a truck a month ago, was held at the residence, 2403 Carondelet street, at 10 a.m. Friday. His death is honored in special orders no. 4, 1920 U.C.V., dated August 26, 1920, which says in part: "A loyal soldier, an exemplary citizen, a genial comrade, his passing leaves a void in our fast thinning ranks, while we honor his memor and express our unfeigned regret at his going. By command O.D. Broows, major general commanding: James A. Pierce, adjutant general and chief of staff."
- He was a Lieutenant in the Civil war, was captured (at the fall of Vicksburg) and exchanged twice. He was a prisoner on Ship Island briefly at the end of the war. He wrote a narrative of his experiences over the last month of the war, when he served in a Missouri Infantry unit, attached as a .pdf document on the Louisiana Ancestry page. This is his war record from Booth:
McLellan, Alden, 1st Lt. Co. -, Brown's Lt. Artillery. Appears on Register of Prisoners of War, Taylor's Corps, Paroled May 10, 1865, by authority of Maj. Gen. Canby. Age 29, eyes gray, hair black, complexion fair, height 6 ft. 2 in., Res. New Orleans, La. He may have been a Quartermaster for General Brown.
"Brown's" seems to be what Bergeron calls "Gibson's Battery" (or Miles' Battery), which was later captained by an "M. Brown." On June 30th, 1862 this unit was consolidated with Guibor's Missouri Battery. A brief but complete description of his service appears in Dimitry's Confederate MIlitary History, vol. 10. See also his narrative of his fortunes at the end of the War. He is included on the Civil War page.

This is a birthday celebration for Jefferson Davis, held on June 3rd, 1901 [this is taken by the SHS from the New Orleans, La., Picayune, June 4, 1901.] Note the presence of a relative, W.M.

"The Ladies' Confederate Memorial Association Listens to a masterly oration by Judge Charles E. Fenner.
The crowning event of this beautiful and memorable day was the celebration held at night at Memorial Hall by that veteran organization, the Ladies' Confederate Memorial Association. Within that hall hallowed by so many precious memories, with the sacred battle flags floating all around, with the portraits of the immortal leaders of the Confederacy smiling from the walls, and everywhere the holy trophies and relics of a time that can never fade, the battle-scarred veterans gathered at the call of the noble women of the Memorial Association and just as this old and honored body pinned the colors of the Confederacy on the Louisiana boys who marched forth to death and glory at the first call to arms, just as they watched and waited and wept with them through all the dark days that followed, so now after the lapse of nearly forty years the organization, with its ranks thinned of those early workers, but with their noble daughters taking their places, again stood with the veterans, this time to renew the past, and, above all, the glorious history of the immortal chieftian who stood for all that the Confederacy represented, Jefferson Davis.
The hall was packed to the very doors; from the steps on the platform to the extreme end of the hall standing-room was impossible. It was a magnificient audience, representing the talent, the chivalry, the glory of the South's best heroes, and its most loyal and patriotic women.
The hall was brilliantly illuminated. Upon the platform stood two pictures of Jefferson Davis, the one entwined with the army, the other with the navy colors. Above was suspended a wreath of ivy,  the symbol of undying remembrance. The banner of the Ladies' Confederate Memorial Association and the flags of the United Confederacy hung on either side, and upon the tables glowed the red, white and red—of the Confederacy—culled in flowers from the garden.
Seated upon the platform were: Mrs. Wm. J. Behan, the able and devoted President of the Association, and the following officers of the organization: Mrs. Jos. R. Davis, Mrs. Lewis Graham, Mrs. F. A. Monroe, Miss Delphine Points, Miss Kate Eastman, Mrs. Alden McLellan, President of the Daughters of the Confederacy, Mrs. E. H. Farrar, Mrs. J. R. Davis and the Misses Davis, relatives of the great leader; Judge Charles E. Fenner, orator of the evening; Dr. Brewer, of the Army of Northern Virginia; Commander J. A. Harral, of the Cavalry Camp; E. P. Cottraux, Sumpter Turner, General Adolph Chalaron, General Alden McLellan, W. M. Fayssoux, Colonel John B. Richardson, Judge Frank A. Monroe, Samuel Allston, Rev. Gordon A. Bakewell.
Mrs. Wm. J. Behan graciously presided at the services [ . . . ]"
He was a Duke of Rex in 1911. His name regularly appears in newspapers at this time, 50 years after the war, about his activities in Confederate veterans associations. His wife was also very involved with this.
A letter of his is preserved as item B363 in the Civil War Manuscripts Collection of the MIssouri Historical Society Archives to Joseph Boyce, dated March 20, 1919, requesting information about Missouri veterans for the United Confederate Veterans.
According to family history, "at some period the shipyard and towboat line [which Alden and his brothers had run] were liquidated and Alden ended up with real estate and presidence of the St. Charles Street Railroad. . . . Alden furnished the money to start up the Alden Mills, at textile mill in New Orleans, and Meridian, Mississippi" [which his son Asahel ran].
He was hit by a truck on Canal St. in New Orleans, and died a few weeks later at age 84; For more about his family, see the biography under his son William H.
He is buried in the McLellan tomb in Lafayette Cemetery; here is the inscription:
