If what you posted were taken for all that it entails. Then where someone was born or to whom someone was born is no determination to being a natural born citizen. Those persons mentioned must of had to have met some unstated criteria. Otherwise Anyone could have been declared a natural born citizen. Who were those persons, and why were they declared citizens at all. We simply don’t know.
The point of looking at the acts was to show how the Massachusetts legislature used the two terms natural born citizen and natural born subject interchangeable.
I didn’t include the entire act but only the parts relevant for that purpose. Reading a complete act sometimes shows the place where the people were from, for example for the November, 1788 act:
Elisha Bourn, Sandwich, late subject of Great Britain
Seth Perry
Edward Bourn
Richard Devereux, Parsonfield, late of Ireland
William Jolly, Portland, late of St. Pierre, Martinico
Jeremiah Joakim Khaler, Boston, late subject of Denmark
Phillip Theobald, Pownalborough, from Hesse Hannau, Germany
John de Polerisky, late of Molsheim, in Alsatia, France
These were immigrants who had taken the oath of allegiance required by Massachusetts.
“Otherwise Anyone could have been declared a natural born citizen.”
They were not being declared natural born only that they had the same rights as natural born citizens. Just as naturalized US citizens today have the same rights as natural born US citizen except the ability to be President or Vice President.
