Researching a family name in the JC archives, Kenneth Keller found a report in an 1895 edition about a Torah pointer (yad) Charlotte Schoenfeld had presented to Dublin Hebrew Congregation, Adelaide Road, to celebrate the marriage of her daughter to Mr Keller’s paternal grandfather.

After negotiations with the Dublin congregation, Terenure, now in possession of the “handsome pointer of gold and silver filigree”, the yad will feature in the barmitzvah ceremony of his grandson, Benjamin Gershlick, on Shabbat at Borehamwood and Elstree Synagogue.

The Dublin shul was initially reluctant to lend the pointer, one of its oldest pieces of Judaica.

“As a last resort, I was prepared to fly over and get it and then bring it back,” Mr Keller said.

That was not necessary as a Terenure member visiting London this week brought the yad over.

Mr Keller said he and his grandson were“really excited” about the historical connection, which he hoped the rabbi would refer to in his sermon.
