My grandfather, Cornelius Francis Birkhoff was born in Passaic. His father Vincent V. Birkhoff, a Passaic Police Sergeant, was born in Paterson 2/11/1880 and lived in Passaic until 1953 when he was killed in an automobile accident in Illinois. I am searching for the three brothers and one sister of Vincent. As of September 28, 1953 they lived in the following locations: Frank Birkhoff in Passaic Adam Birkhoff in Passaic Henry Birkhoff in Wayne Frances (Fanny) Birkhoff married Charles Lembeck and lived in Clifton. Charles Lembeck was a Fire Lieutenant in Clifton. In 1956 the family moved to Virginia and all contact with the rest of the Birkhoff family was lost. I would like to find my family if possible. Any help would be appreciated. Vern Ferguson Roanoke, VA
