The locations are known residences of the husband, ending with the husband's place of death.  An entry in Torrey does not imply a marriage in New England; it only demonstrates the presence of a married couple there before 1700.  Torrey is a compilation of published sources, not primary records, so he should be considered a secondary source.

NOTES... ...In Phillimore and Gurney's Buckinghamshire Parish Registers, vol. 6, pp. 10, 11, occur the following marriages at High Wycombe...      Chaddus Browne & Eliz. Sharparowe  11 Sept. 1626... The date of Chaddus Browne's marriage, as above, and the first name of his wife are right for Chad Browne of Rhode Island.  The locality seems likely, judging by the names of his associates as shown by Sylvester Baldwin's nuncupative will.
