Thanks, that is very interesting. I did some more digging. In that same publication, Page 603 , it explains that this is not a probate case. (dd is not a term used in any of the three volumes of probate records.) I found more references to this court case:
- Collections of the Connecticut Historical Society Vol. 22: Records of the Particular Court of Connecticut 1639-1663, Page 99-100.
- The American Genealogist (1991) Vol. 66, Page 31.
The TAG article says that dd means "delivered", but this term may imply they were "indentured servants". It appears that the Particular Court records use "dd" often to mean something has been "delivered" for a fee. Delivered, as in a transaction between two people.
