According to the 1900 census (Ward 5, Troy, Rensselaer, NY), Warren R. Ross was born June 1893, son of Nelson D. Ross (b July 1862 in New York) and his wife Edith A. _____ (b Dec 1867 in Virginia). Nelson and Edith had been married 8 years (i.e., m about 1892). Warren was their oldest son. In 1900, he had the following siblings: Earl G., b Dec 1894; Nelson D [Jr], b Sep 1896; Eugene F, b Mar 1898; and Elois, b Oct 1899. His father, Nelson, was a musician.
In 1910, the family is still in Troy, and we learn that his father Nelson played the clarinet. Warren has three additional siblings: Edith A (1904); and twins Donaldson G and Dorothy E (1905).
In 1920, Warren is working for a telephone company in Brooklyn, NY, married to Sonia, probably Ziv (because living with them is brother-in-law to Warren, Robert Ziv); Warren and Sonia have a daugher Elaine, just over 1 year old. Sonia and her brother Ziv are from Russia, of Jewish descent.
In 1930, Warren and Sonia are still in Brooklyn. And they've added a son, Earl W (b abt 1926). Sonia emigrated in 1910. Warren is now manager of a bookstore.
In 1940, we find Sonia, widowed, still in Brooklyn, owner of a bookstore and living with her two children.
Warren also registered for the draft for World War I Jun 5, 1917, at which time he recorded that he was 23. At this time, he was living in Newark, New Jersey. He was described as tall, medium build, blue eyes and light brown hair.
He died in 1934; an obituary/death notice dated 22 May 1934 ( NOT his death date), indicates he was the proprietor of a bookstore, and was of Flatbush Avenue; he'd been the secretary and one of the founders of the Flatbush Dependable Merchants. He died of a heart attack in his home, 1116 Flatbush Avenue, age 40. (Yikes.) Survived by widow Sonia, and two children, Elaine and Earl. (Ancestry.com.

A longer obituary indicates that the bookstore was also a lending library and maintained at his residence. The funeral was held at Moedinger Funeral Home and he was cremated. (Same source, image 10354)
