A Nellie Batzer died as an infant and was bured in Cleveland on 29 Jun 1886. But based on the 1900 census this Nellie survived childhood and was age 13 at that time.

Might be Nellie B. Lingreen or Lingruen, wife of Albert C., who was born 23 Dec 1880. Deceased 11 Jan 1942. Buried 13 Jan 1942 in Lake View Cemetary. All in Cleveland. But age shown as 55 with estimated birth date in 1887 so could be a match.

Nellie was not listed as a surviving sister when George died in 1944.
