I have the eldest son of JOHN BEERS and ELIZABETH REID as ROBERT WILLIAM BEERS, born 23 Aug 1848 South Branch Kent Co. who died 18 July 1935, he married ELIZABETH FAYLE born 1839 who died 1959 burial for Robert and Elizabeth was at Richibucto Protestant Cemetery.
Some BEERS info is found at this REID family website however, I caution you to double check the resources as I've noted some mistakes but it is a good starting point for researching either family.
