Known as Nancy, Ann Balchen was a constant source of anxiety for the family. Her behavior was wild and reckless, causing consternation and embarrassment.  In the 'Cumberland  Letters' by Clementina Black she is quite often discussed by her cousins the brothers Richard and George in despairing terms.  For instance on Page 42 .... 'The missing letter must also have conveyed some information of the affairs of Ann Balchen, the sister of Mrs. Cumberland [Elizabeth Balchen], whom from the circumstance of her nephews always spoke of her as "Nancy", I [Clementina Black] surmise to have been considerably younger [three years].  She was evidently an ungovernable person, and had, I believe, been recently imprisoned for debt [around 1773]. She did not live many years longer and may possibly have been suffering from obscure brain disease which lead to violent and irresponsible conduct:

"I am shocked to hear what a miserable situation Nancy has reduced herself to by Her Folly & impudence, tho this is no worse than what every Body who knew Her expected.  I think however something she ld be done for her at least to prevent Her being driven thro real Want to bring further disgrace on Herself and Family"  --
