I've looked in Delaware a little, mostly by reading "The Swedish settlements on the Delaware, 1638-1664" by Amandus Johnson. He was a Lutheran preacher sent by the supportive Swedish Crown long about 1750. According to his roster there were at least three families named Jonsson. I've not found any connections to them from my Johnsons who were in western Kentucky long about 1808-1812 and in SE Missouri since 1812. Amandus was fairly grumble about how the younger generations had forgotten most of their Swedish heritage and language and had mixed in with the "local" English. I found a couple other books on that settlement, but were not as genealogically useful as this book. Gerald J.
