I'm trying to identify the source for a reference that came with a gedcom import but seems to have been lost. I've tried looking in the change history, and related profiles. Also looked at the page #'s in Torrey's sources for clues, but no luck:
Source: #S20 Page: p 355 & 356.
Unfortunately, the information provided in the source doesn't seem to be duplicated in other sources referenced. Since its about his family origins so quite important. Oddly, in the Great Migration sketch, Anderson names Thomas's parents but doesn't provide a reference.
If I can't find this source, any source that I can use that supports the information about his parents and the comment: "The Thomas Southworth who came to Plymouth should not be confused with his uncle, Thomas Southworth, who stayed behind in Leiden." would be great.
(Tagging mayflower because there seems to be some source overlap with his daughter Elizabeth marrying Joseph Howland, Mayflower descendant).
