Because the Brownrigg names and its variations seem to originate in the British Isles, it will be interesting to see if lines tested originate from one common ancestor or from several different ancestors using similar surnames. Some of the project goals are: To identify ancient family origins. To sort participants into family lines according to dna results. To identify various surnames that are part of the same Brownrigg family. To prove or disprove a research theory and to correct incorrect information. To direct research to specific geographical areas and time frames. Provide contacts between researchers who can share paper research.
