Saul was the son of Calvin Haddock and Mettie Buck. He married Ida Holloway abt 1908, they had 14 children according to 1920-1940 census records and transcriptions in the Book Haddock Heritage 4th Edition. During research there was a Haddock with Saul and Ida listed as parents that was born 26 Jul 1922 a date different than all the other children listed, Its possible this was an infant that died early since it is not listed on any of the census records.

UPDATE: This child born on 26 Jul 1922 has been discovered to be Lester Haddock after a volunteer who visited the grave emailed me regarding a Lester she found. This memorial has been updated to reflect correct birth and death dates of Lester Brown Haddock as 1922-1924.

UPDATE: 22 Nov 2019
An obit located on genealogybank.com named Saul as Claude Haddock, it lists Ida Holloway as spouse and named three daughters and seven sons as survivors, see attached photo.

It was also discovered that Russell Haddock is actually Runnell Haddock, the birth index spelled the name incorrectly. Because of the spelling it was assumed he was a male even though sex was not designated. A 1940 census which named a Runnell, lists her as a daughter.
