Linda, The 1840 census only gives the name of the head of household, not of any others in the home. Other occupants are indicatred by sex & age range. I found your Sumners on the 1850 census & typed the record below. In 1840 there were two Palmer sumners in NY. One was in Boston, Erie Co. & the other in New York ward 1, NY, NY. The one in Erie Co. has the correct number of people in the right sex & age ranges to be your Palmer. Pat R.
