There are other "Kositsin's" buried at the cemetery. I don't know if there is a relation to Vladimir. It appears from name alone that Nefed Nikolai would be related. They include:
Kositsin, Nadejda Ilin (Unknown) (1882-1978)
Kositsin, Nefed Nikolai (1915-1977)

Kositzin, Anastasia S (Unknown) (1886-1966)
Kositzin, Evdokia E (Unknown) (1884-1976)
Kositzin, John Simon (1883-1959) & Uleyna M (Buyanova) (1884-1981)

California Passenger and Crew Lists, 1893-1957
Name: Vleadymir Kositsin
Arrival Date: 30 Apr 1922
Gender: MALE

Ship Name: Persia Maru
Port of Arrival: San Francisco, California

Kositsin, Nadejda Ilin is the Vladimir's siter-in-law.
Kositsin, Nefed Nikolai is the Vladimir's nephew.

There is another Vladimir's nephew at the cemetery. He is the Kocitzin, Leon Nikolay with different spelling of his family name.

Kositzin, Anastasia; Kositzin, Evdokia and Kositzin, John are probably not related to Vladimir.
