Also I believe Alexander Maules wife Margaret Hall died 22 January 1850 although this is probably her burial date. Whats not helpful is her death certificate says Margaret Hall, daughter of Alexander Maule.
We know its not Alexanders daughter Margaret Maule because Margaret married Francis Maule (possibly a distant cousin) 2 May 1851 then emigrated to Victoria, Australia in 1855 where she gave birth to another of her children on 29 Mar 1855 at Immigration Hospital, Portland, Victoria, Australia. Her death certificate names her father as Alexander Maule and mother as Margaret.
Margaret dies 26 Jan 1882 in Ballarat, Victoria, Australia and is buried in the Ballarat Cemetery.
Alexander Maule remarried to Elizabeth Simpson on 2 May 1851 in Alloa, Clackmannanshire, Scotland.
