I have a connection to a Jacob and Samuel Booz who were brothers, born 1836 and 1850, respectively. I have no information on their dates of death to verify with the cemetary record. Their mother was an Elizabeth Booz (married name) but seeing that she was born about 1811 it is a stretch to think that she lived long enough to be the same Elizabeth in the plot. Let me know if this helps, it has been some time since the original post.
