Simha Salomon Abandalac

Sister of Ester Abendalac ? and of Mozes Salomon Abendalac ?
Answer: Yes. From Dutch records, all were born in London to father Salomon Abendalak (Ben-Dalak/Ibn-Dalak"), and we know that Salomon was involved in Bevis Marks community in London at that time, and we know from Bevis Marks records that he married Rachel nee de MATOS on 1st March 1713. So we can safely assume that they are all descended from the same Salamon and Rachel who married 1713.

Age on marriage bann was 22 making her born approx. 1714. This fits in with the time line of the assumed parents who married in London in 1713. She was the oldest.
