My husband is the grandson of Ivah Adams (daughter of John Quincy Adams II and Alice Abbey). John Quincy II was the son of John Quincy Adams and Nancy Thomas. Ivah was born 9 Dec 1905 in Madison, Lake County, Ohio, she married Roy Gieseler, and 2 Apr 1978 in Bradenton, Florida. Her brother was John Quincy III. He was born 4 Jul 1908 and died 7 Jun 1982 in Deland, Florida. His spouse was Hazel Adams. I can share more.
