John Turner, (later styled John Jr.) the younger brother of John Turner and son of Humphrey and Lydia (Gaymer) Turner, was born about 1624/5, possibly in Little Baddow, Essex, England. John's younger sister Lydia was baptized at Little Baddow, Essex, England, on 17 Feb 1629,  leading to speculation that John may have been baptized in the same parish, Little Baddow. John's older brother John was baptized in the parish of Terling, Essex, on 24 Mar 1621.  Anderson also puts John's birth date at 1624, but was published two years before the discovery of the records in Little Baddow and Terling, and does not speculate on a location.
John Turner Jr. married Anne James on 25 April 1649 in Scituate, Plymouth Colony.
Note: Supposed son Caleb, as shown in A New Look at The Family of Francis and Philip James of Hingham: Immigrant Ancestors (NEHGR 151:71)
appears to be an error in reading of the "Scituate, Mass. Second Church Records" where the baptisms of Jacob and David Turner are immediately followed by Caleb and Samuel Cushion.
