In 2005 I received this in answer to a query to the Nova Scotia Archives and Records Management
"Allan E Marble's Deaths, Burials & Probate of Nova Scotians from Primary Sources records the death of Lt. Arthur F Duncan, RN 30 September 1790 and the death of Lt Thomas Twisden 14 December 1790 . The daughter of Lt Twisden and Isabella Duncan, Isabella M Twisden died 21 August 1792."

Does this work indicate the individual primary sources for each entry? And if so how do I access the original sources? How do I locate a death certificate?

I would also like to check the accuracy of this information as "the death of Lt Thomas Twisden 14 December 1790" doesn't match my other research findings - I suspect it may, in fact, be his marriage date but I cannot see how that could come from a work entitled "Deaths, Burials & Probate of Nova Scotians from Primary Sources"

Any assistance appreciated
