I have several of the RIX family in my family Tree.

Joshua Platt RIX called (Holy Jo) married Martha NIGHTINGALE in the parish church of St. Mary, Newington, Surrey, England on 07 May 1846. Her parents were Robert NIGHTINGALE and Martha LAVER.
Joshua's parents were George RIX (clergyman) and Mary Ann ClARK who married at Bothal, in 1810.

Martha's eldest daughter Elizabeth (Betsy) born 18 Feb 1839 in Walworth, Surrey, England and married George MASON from Okain's Bay, Banks Peninsula, New Zealand, when his first wife Heni MAHAKA died.

George MASON had fifteen in his family, their eldest surviving child from the marriage to Elizabeth Nightingale/Rix being my gr. grandmother Mary Ann MASON born 02 Dec 1857 who married Charles Samuel Frederick MOORE.

Many more details can be found on my Moore forum.
