In the previous post which showed an image from Newington College (http://www.newington.nsw.edu.au/) showing what was thought to be Jean’s second eldest son, Hippolyte; quick email off to the school’s INCREDIBLE archivist, David Roberts, has since set things straight.
The Serisier boys in the picture are in fact Hippolyte’s younger brother’s, Lavigne and Frederick.
David Roberts has sent a wonderful collection of images in which the Serisier boys feature as members of various Newington College sporting clubs.
