In my research into Robinson,the name was spelled Robertson on some of the Census but family used Robinson.Were in VT (Joel)& Candor , Spencer, Barton/Waverly( Willis).Lum was in Barton/Waverly & I think Dryden(Rev soldier).Do not recall any Lewis or connection to Lum on these.Daughter went to west coast.Her brother Peter Lum settled in Wash Territory.There are letters in the WA. Museum from Tioga Co NY in a trunk,but no one seemed interested & could find no one in Tioga Co of the family.Book & pictures "Port Madison WA "much about Lum.
