1729 is before most census records that would tell you where someone was born. My family was also in NC around the time, although my family went to Pasquotank county from Elizabeth City in the Jamestown area. The best bet would be to see if you can find an ancestor on a ship list as see if there is any more information. I often use the site below when looking for early colonists.

Many of the people that moved to the Carolina colony in the early 18th century because of religious pressures in the other colonies. Massachusetts Bay was Puritan and Pilgrim while Jamestown was Church of England. Many Welsh colonists were non-conformists, what we would call non-denominational Christians today. There were also many Quaker families from Scotland that went to the Carolinas in those days. Either way, non-conformist and Quaker records from the time are few and far between.
