An Ohio hospital paid the estate of astronaut Neil Armstrong $6 million in a confidential agreement to settle allegations that post-surgical complications led to Armstrong's 2012 death, according to court documents and a report in the New York Times.

The 2014 settlement went to 10 family members, including Armstrong's two sons, sister, brother and six grandchildren, according to documents filed with the Hamilton County Probate Court in Cincinnati which were publicly available on Tuesday. Armstrong's widow, Carol, did not receive any money in the settlement.

Armstrong's sons, Mark and Rick, contended care provided by Mercy Health-Fairfield Hospital cost their father his life, according to the New York Times.

The 50th anniversary of Neil Armstrong's first steps on the moon was celebrated Saturday. He died on Aug. 25, 2012.

A Sept. 24, 2014 motion to seal the settlement said the hospital and its caregivers stood by the treatment they provided.
