Sarah was married to Robert Borden sometimes spelled Burden.
I am trying to find any proof that her maiden name was Mckenzie. She is listed in the Maitland 1871 census as 53 yrs old living with daughters Annie, Emiline, Rachel, Sarah and grd Jane. Rachel married Simon Mattatall-Emilene married James Brison-Sarah Jane married Henry Dalrymple-Annie married Joel Dalrymple. She is listed in later census as living with daughter Rachel Mattatall. On Rachel's death certficate her son states Sarah's maiden name as Mckenzie. I cannot locate a death certficate for Sarah or her husband. Sarah had another daughter Mary who married and moved to the USA. If anyone has any information on this family it would be a great help.
