PVT James Yanchuk grave site found!
Thanks to Andrea I was able to learn that PVT Yanchuk is buried next to his parents at Sts. Peter & Paul Russian Orthodox Church Cemetery in South River, NJ (Middlesex County) There is a very interesting history of the church and cemetery at: www.saintpeterandpaul.org/history.html
His sister, Mary, is the lone surviving member of the family and thinks it wonderful that people will remember her brother.
PS: I found a listing for Holy Ghost Carpatho-Russian Cemetery in Bound Brook, NJ.
