John Mills married Elizabeth Show April 6, 1653, whose children are as followeth.
...
Nathaniel Mills was borne April 22'd 1672.
[Note, also p. 650:
Nathaniel Mills son of John Mills & Elizabeth his wiffe borne 12, mo. 22, 1672.
Note: no baptism for Nathaniel is found in Quincy church records. (Page 38 (viewable at Family History Centers)) says "Baptisms beginning with the year 1672. The Rev. Moses Fiske was ordained Pastor of this Church September 11th 1672. No records of the church to be found previous to his time." The first baptism is 22.7.1672 [22 Sep 1672]. Since Nathaniel's sister, born in 1675, has her baptism recorded (p. 40) making it appear the family were members of the Church, the absence of a baptism for Nathaniel suggests his baptism was before the date baptisms start, hence supporting the April 1672 date.]
