Yes, you found the correct information:
On "Find A Grave" you list the following: "Emma Jacob (Shubin) Martino is the daughter of Jacob Elia'vich Shubin (1882-1917) and Fedosia Tamalin (?-?). She is one of three known children: Emma, Martha and Martin.
"She married three times. She first married Peter George Shuteroff (1902-1974) before 1920. They have a son Peter. The marriage probably ended in divorce. Emma's second husband was Arthur Fellows (1883-1956). They have eight known children: Arthur, Edna, Martha, Eva, Percival, Larissa, Theodore, and Ralph. Emma's third husband was Guy Martino."
You then link Jacob Elia'vich Shubin to "...Elia Vasilli'vich Emil Shubin and Fenya Uraine. He is one of seven known children: John, Jacob, Abram, Michael, Anna, Moisey, and Manya."
Parents: Jacob Elia'vich Shubin (1882-1917) and buried in Olivet Memorial Park, Colma, CA; and Fedosia Tamalin
