 During the Civil War, he was a member of the 84th NY Vol. Infantry Regiment.  After the war, he joined the 48th Regiment, NGSNY, which was headquartered out of Oswego, NY.  Company B of the 48th Regiment was located in Hannibal, NY.  At various times, he held commissions as Second Lieutenant, First Lieutenant, Captain, Assistant Surgeon and Surgeon.  He also was Surgeon of the 20th Separate Co., serving 23 years.  In addition, he was 10 years Examining Surgeon for the United States Pension Department.

Acker was likewise active in civil affairs, serving at different times as Supervisor, Postmaster and Town Clerk of Hannibal.  His medical office was located on the east side of Cayuga Street just off the Village Square in the Village of Hannibal.  He is buried in the Hannibal Village Cemetery.
 According to his obituary:  "Dr. Acker was a man held in very high esteem within the community where he lived for so many years and far beyond that community, because of his lovable and magnetic personality and many gifts and graces.
 Very many have a deep sense of loss and grief because of the departure of one, who was so tender and skillful in his ministrations and so solicitious for their welfare.  He was a gifted man intellectually.  Coupled with a well-balanced, well-informed intellect was excellent judgment.  His wise judgment  and keen perception were much relied on.
 Thus he was fitted to be a leader amongst men, and his fellow-citizens showed their appreciation and confidence by entrusting him with high and responsible positions.  His emotional gifts were on a par with his intellectual.  His generosity and considerate kindness were unbounded.
 The departed was a man strong and steadfast in his convictions.  He was loyal, tenacious of those principles he thought were rirht.  He was distinguished for sincerity and integrity.  Dr. Acker was a very busy and active man.  Handicapped and weakened as he was by growing physical infirmity, he managed beyond his strength, continued in the work dear to his heart until near the end, ministering to others.  He was faithful to the end.
 The departed was a soldier in the Civil War.  His comrades recall his loving presence; his thorough and sympathetic knowledge of the stirring events of that crisis.  A prominent and faithful member of the Board of Pensions and in other ways he had done a great deal to promote the welfare of the verterans and their families and was laborious and practical in everything that concerned the highest interests of the Post of which he was a loyal and devoted member."
 Dr. Dillon F. Acker died at his home on Auburn Street in the Village of Hannibal at 8:15 AM, on Thursday morning, October 28, 1909.  The funeral service was held at the family residence on Saturday, October 30, 1909, at 2 PM.  The Rev.

ii. HELEN (NELLIE) MERCELLE ACKER, b. 1881, Hannibal, Oswego Co., NY (Source: Gravestone in Hannibal Village Cemetery.); d. 1971 (Source: Gravestone in Hannibal Village Cemetery.).

Notes for HELEN (NELLIE) MERCELLE ACKER:

 

Helen was always called Nellie by those who knew her.  She never married and lived on Cayuga Street in the Village of Hannibal until her death.  Her house was the first house after the former apartments (now torn down) on the east side of Cayuga Street headed south from the Village Square.  She donated land which faced Auburn Street and backed up to her own home  on Cayuga Street to the Hannibal Fire Department so they could construct  a larger firehouse in 1946.  After the Hannibal Fire Department built a completely new firehouse on Oswego Street in 1964, this building was occupied by the Hannibal Free Library.  After the Library moved to the newly renovated Hannibal Community Center on Oswego Street in 1979, the building became the Hannibal Town & Village Hall.
