Notes for: Sarah _____
Possibly Sarah Tabra(ha)m, sister of Louisa and Elizabeth, which would explain Brooks Samuel Pamplin and Sarah M Thompson being her nephew and niece. However, no appropriate baptism found for her.
Another possibility is that she was Sarah Hallack, married Samuel Brooks 1829 Cambridge All Saints.
Cambridge Chronicle 28 Dec 1878:
