Mrs. Kate Adams Keller was an extremely caring mother. She was the second wife of Mr. Arthur H. Keller and quite younger than him. Towards Helen,she was more caring and responsible. Before Miss Sullivan's arrival, she was her loving refuge.  Whenever Helen had a tantrum of frustration on account of being unable to express herself, she would go into her mother's arms where she would forget the cause of her tempest. Her mother was very much concerned regarding Helen's education. She was always requesting her husband to arrange for her education. It was she who saw the hope of the possibility of Helen's education while reading the account of Laura Bridgman. She wanted Helen to be educated like her. She also felt very sad on knowing that Dr Howe, who had taught Laura Bridgman, had died. She was always in search of finding out ways to make life of Helen more comfortable.

Arthur H. Keller was Helen's father. He was retired captain of the Confederate Army. He was an accomplished hunter and farmer. He was known in the neighborhood for his hospitality and horticulture skills. Often he told Helen interesting stories.  He was a great father who loved Helen a lot.  Her father was also very much concerned about her. When he heard about an eminent oculist who had been successful in many hopeless cases, he at once decided to take Helen to Chisholm in Baltimore. He examined little Helen and expressed Helen's blindness could not be treated. He advised Helen's father to meet Dr. Graham Bell in Washington. Helen's father immediately took her to Dr. Bell. Dr. Bell referred him to Mr.Anagnos, who promised him to arrange a special teacher for Helen. The news of his sudden death left Helen sorrow-stricken. Helen loved him a lot.
