Complicated Ruth.

We have one last Simpson to do. Mary's baby sister Ruth. Mary was 18 when she was born in 1829. In 1836 she was 7 when big sister Betty married William Cooper.
In 1853 when she was 24 she married, Ruth Simpson + Jonathan Duxbury St. Mary Blackburn CE12/16/251.

I think she was widowed in 1855.
1855 Jonathan Duxbury age 28 Darwen Blackburn D/14/50

I have not found an exact death for sister Betty (Cooper) but Ruth married her husband.
1856 William Cooper + Ruth Duxbury St Mary Blackburn CE12/20/13
