Finding a grave in Ybor City

My great-grandfather was away from his home in northen Alabama and was working in an orange grove in Seffner when he fell victim of the 1918 influenza pandemic and died. I understand that he is buried in a mass grave in Ybor City. I would love to have a photo of any marker. His name was James Harvey Garland, 19 Apr 1877 - 23 Oct 1918.
