Revisiting an old research project: The Origins of the St. John family

Back in 2014, I worked on the origins of the St. John family at the Salt Lake Institute. The debate was between the family being from Antwerp in the Spanish Netherlands [now Belgium] or having roots in Wales.

My conclusions at the time leaned toward Antwerp, but not with absolute certainty. That research project has gathered dust since then.

Loose ends existed on both sides of the argument. The time has finally come to try to tie up those loose ends.

I have plenty to examine:
[1] a copy of the article that promoted the Antwerp origin.
[2] a rebuttal article stating the case for Welsh origins.
[3] my own research on both theories.
[4] numerous articles on the Welsh families.
[5] my SLIG project report and summary findings.

Perhaps I missed something last time around. One item is missing from the Welsh research that is crucial - the will of Thomas St. John's will. Likewise, similar documentation is missing from the other side.

What is known:
[1] Matthias St. John, the immigrant, was the son of Christopher St. John.

What needs to be determined:
[1] Was Christopher born in Antwerp, Wales or possibly London?
[2] Was Christopher's father Mathias of Antwerp or Thomas of Wales?

Let the fun begin!!!!
