A better picture is needed to read the date, but I'll translate what I can:
"Here lies the woman Malka Gold, daughter of Eliezer Zvi, died 9th(?) of Tevet(?) 56xx(?)."
Sagan/Shagan family from Veliuona (Velon), Lithuania
Goldberg family from Vidukle, Lithuania
Susselovitch/Zuselovitch family from Raseiniai (Rassein), Lithuania
