Charles and William Bixley Names

There is a striking similarity between the names of John and Grace Bixley's descendants and those of Richard and Mary Bixley.  The similarity is most obvious in the names of John and Grace's son Charles' children and Daniel and Elizabeth's son William's children.  If our John was the son of Richard and Mary Bixley, Daniel would have been his brother and so Charles and William would have been first cousins.  The table below shows the similarity - the names highlighted in green show a match with Charles and Jane's family.
