Hi Ian … it looks like our families might be linked. My Catherine was born in Brinkworth (1777) and married John Harding Dixon in 1801 in Brinkworth. Their son John Dixon (b.1808) is my gg grandfather and following that line, my g grandfather was Reuben Dixon b.1836 in Grittenham, Wiltshire, and my grandfather was Mark Dixon b. 1873 in Brinkworth. Incidentally, I must correct my previous email – Catherine was my ggg grandmother.
One problem, I have Catherine’s father as John Vizard (b.1738) and her grandfather as Thomas Vizard (b.1719) – not John.Regards Peter
