This is an update of a post on the family of Isaac CASTLE and Harriet LEWIS in July 2008. I've had no luck finding the death of Harriet LEWIS yet, and ordered a death certificate of their youngest children (twins, both died a few months after being born in 1872) to see whether Harriet expired with them due to difficulties.

Death of Harriet nee LEWIS not yet determined and there is no indication she died during/after labour in 1872, but it is known from Isaac's obituary that she predeceased Isaac CASTLE by a significant period of time. Isaac CASTLE died 1911, Cowra District Hospital, Cowra, NSW.
Most sources are the NSW BDM indexes, and in some cases the actual certificates themselves. Spelling varies - Castle, Castles, Cassell mainly. Death of Abraham and Isaac from the Bathurst Lonely Graves Register.
