I have recently discovered that my Sarah Ann Uttley, born Heptonstall, Yorkshire, in 1827, married Thomas Bagnall in Manchester, Lanchashire in 1849. The Marriage Certificate says that Thomas Bagnall's father was Samuel Bagnall. Thomas Bagnall was born about 1824. I wonder if your Samuel Bagnall was the brother to Thomas Bagnall and that his father was Samuel Bagnall. Unfortunately, I believe that Thomas Bagnall first husband of Sarah Ann Uttley, died in 1850. In 1851 James Bagnall, son of Thomas Bagnall and Sarah Ann Uttley, was born. By 1854 Sarah Ann (Uttley) Bagnall remarried to my gggrandfather, Charles H. Marshall and they immigrated to Boston in America in 1854 with Sarah's son, Jamres Bagnall.
You mentioned that your Samuel Bagnall married Frances Smith. My Sarah Ann Uttley was the daughter of James Uttley and Betty Smith, both of Slack, Heptonstall, Yorkshire.
