We have several family plots in the old historic cemetery in Rome GA. It is sobering to see how many little babies (and young wives in childbed) we lost in the old days. My grandfather had an older sister named Leila who died at 4 months - her little gravestone has a lamb on it and the legend, "Ere life's thorny path she trod/ Angels called her home to God."
I checked with our priest, and he can simply consecrate our family plot when the time comes. There's room for 3 or 4 more, or as many as 10 if we cremate.
Our suburban parish doesn't have enough land for a cemetery -- there's a tiny memorial garden where ashes can be interred, but that's it.
