If you will check the NEHGS you will find a volume with The Rich Family of Eastern Connecticut by Edwin A. Hill. I am sorry that I can not tell you the volume no. as my copy is old and has faded but it starts on page 222 and maybe someone else knows the volume. It has some information on the children of Cornelius in it which may help you. I do not know if this is where Evelyn Rich got her information but I do not think so as I believe the volume that this is in is after vol. 83. Good luck on your search.
