This compilation is from the synagogue’s administrative records. This listing should absolutely NOT be interpreted as a list of past members. The placing of a plaque by a congregational member was to honor a family member, who may or may not have been a member of Keneseth Israel. An example of this is found in the case of Private Issac Snellenberg, a Civil War casualty. There is no record of his family’s membership until the 1870’s.
Also, in researching the five names on plaques honoring those who died in World War I, it was discovered by referencing military and pension records, that two of the dates of death were incorrect.
Cross referencing entries on this list with marriage records, Confirmation Class lists, and the Religious School Registry Book MAY enable one to ascertain membership affiliation.
