In their wonderful book, The Jews of Jamaica Tombstone Inscriptions 1663-1880 (FHL book #979.92 V3), Richard D. Barnett and Philip Wright, list the burials of 2 sons of Jacob Henry De Pass and his wife Louise Alberga. Those sons, George Cecil and Arthur Rich are buried in Kingston, Jamaica at the Orange Street Cemetery. While it is possible that these are the only 2 children in the family, another record to search would be helpful in finding out if that were true.
