The information confirming the burial and biographical details is from Congregation Emanu-El Burial Register 1861 – 1866 as related through the JewishGen Online Worldwide Burial Registry (JOWBR). JOWBR states this was one of 2 twins but has no further information as to the birth or death dates, nor any definite information as to parentage.
When the grave was prepared for Hinda Shapiro (D-54) small bones and small metal handles were found. It is thought that these are the remains of the Sylvester twins.
It is possible that these remains were children of Frank and Cecelia Sylvester.
There is also a record that William Bill Sylvester, son of Frank and Cecelia Sylvester and his wife E.E. (Daisy) had twins who were born on February 12, 1906. One died on February 12, 1906 and another died on February 24, 1906.
It’s hard to tell which set of twins were discovered in this plot.
