Hi Kaoota, thanks for your reply, like you I have traced the family back to 1708 in Long Buckby, then the Parish records are missing back to 1689, prior to that to 1554, there is no mention of a Newitt, however I do agree with your findings going back to 1534 when a Richard Newitt and Gillian appear, I have built up all the family units and believe that those that went south of the county could be related , and there is a family whose names appear in the early 1700's in Long Buckby that are also in Crick, I do not have any proof of connection only assumption's, and a big gut feeling that they are related.
My research also has been in trying to find as many as possible of the descendants of these early findings, UK is about 200 pages long and the Tasmania/Australia is over 300 page report. So I would dearly like to make contact with you in order to exchange research. Kind regards Bobslot
