Martha and Dominic Schnitzler vs. Joseph L. Ehos, administrator of -ths estate of Joseph Enos, deceased Certified copy of decree quieting title of plaintiff Martha Schnitzler to lot on north side of Soquel Av., Santa Cruz, adjoining Branciforte School lot.
And yes I believe the census may be wrong for if Martha was born 1843 and Immigrated in 1852 to U.S.A. and been married 24 years this would make her 9 years old so census must be wrong, she was born in 1838 in Belledune N.B. Canada and she died in 1924 in Black Land New Brunswick Canada and is buried in Dalhousie New Brunswick Canada.
