St. John Issues

The time line presented in the previous post presents, for me, some issues:

[1] Matthew St. John, as a resident of London, has a relatively complete time line there. A date for his marriage is missing, but a wife Sara/Sarah is named in baptismal records. Births and deaths for children are recorded, A burial is recorded for Matthew. Missing is a burial or second marriage record for wife Sarah.

[2] Events taking place in Connecticut, that involve Matthew coincide with events taking place in London. Baptisms are being held in England at times that it would have been difficult for Matthew to have been there at the time of the child's conception.

[3] Toby St. John was baptized on 5 April 1646 and buried on the 13th. Would his mother have boarded a ship shortly thereafter to join her husband in Connecticut, where she died the following year?

[4] There is no record, to date, of a death in Norwalk, CT for Matthew St. John.

In defense of the Matthew theory:

[1] Matthew St. John's name appears on the Norwalk Founders Monument and Norwalk records.

[2] The names of Matthew and Matthias were used interchangeably in CT records at times. [The sketch on Matthias in the Great Migration 1634-34 discusses Matthias, but is entitled Matthew Sension.]
