Congregants are encouraged to remember loved ones by donating a plaque in their memory. For a one time charge, the plaque is made and installed. Individual plaques are installed where there is room, but every effort is made to locate family members together. The small lights on either side of the name are lit for the full Yahrzeit month as well as during the four Yizkor services during the year. A letter is sent to the relative(s) on file to remind them of the date.
