Each column in the chart below shows one of the family lines where we have a DNA test result. Only five lines are included because we do not yet have a DNA volunteer from either the Worplesdon or West Sussex line. The generation counter in the first column, counts the generations backwards in time. Generation 1 is the person who took the test. The Most Recent Common Ancestor (MRCA) number in the column headers shows the number of generations, counting from generation 1 in that column, where we should expect to find the first common ancestor with the Chobham – Windlesham branch of the family (shown in the table as 'Line 2').
Colour coding is used to show the degree of certainty. A white background shows that the lineage has been confirmed by documentary evidence. The coloured backgrounds show the expected relationships based on the MRCA from the few DNA results available so far. Likely ancestry (yellow background) is shown based on known individuals, but without full documentary proof. More uncertain individuals are shown in green, and complete unknowns in red. But we really need more data to be certain. Ideally we would like at least 3 tests from each family.
