I have searched the 1871 on SP but can't find them.
I thought Charlotte was the obvious choice but searching for Char Barn* gives 3 results and none in Angus.
Elizabeth's husband's name was James.

For those of you who are aware of my quest to find David Mitchell born about 1868 - I have discovered that his son Andrew married Catherine Hughes who was the daughter of William age 2 on the 1881.
This led me right back to William's gran Eliza(beth) Hood - the name of David's mother.
Anyway if anyone can find Elizabeth in 1871 I'd be grateful.
Kind regards,
