"1692. … Jonathan of John & Sarah Mason born Jan. 4."
↑ 1692/93 is inferred to provide an interval between Samuel and Jonathan allowing for the birth of sister Abigail whose year of birth is unknown. If she were born in 1693 as stated by Savage, she would have married Ebenezer Leadbetter when he was 33 and she was 16. Somewhat more likely that she was born 1691.
