Looking for info. on Joseph R. Slater, born 1867 in NJ, married Amanda G. ____ abt. 1894 (place unknown). Father is George A. Slater of NJ. I have Joseph R. Slater in 1880 census in Newark, NJ with his widowed mother, Anna. I also have him in 1910 census in Manhattan, NY. Would like to know his wife's full name as well as where & when they died, any children, etc. Joseph R. Slater also had a brother, George A. Slater, Jr. I don't know what became of him either.
