Here's what I've got so far:

Thomas Southworth (1840-1899) married Ellen Hartley (1839-1915) in 1860.

Their children were:

1860 William (died 1861, age 0)
1862 Benjamin (died 1915, age 53)
1864 John Thomas (died 1928, age 65)
1865 Henry (died 1867, age 1)
1867 Elizabeth Sarah (marr. Herbert Parker 1890)
1868 James ?
1869 Harriet (died 1876, age 6)
1871 William (died 1871, age 0)
1872 William Henry (died 1884, age 11)
1874 Robert (died 1940, age 65)
1877 Ellen (marr. Charles South 1895)
1879 Hannah (marr. John Bernard Tattersall 1896)
1881 Harriet (died 1881, age 0)
1882 Martha (marr. William Henry Ainsworth 1905)
1882 Mary (died 1883, age 0)

Benjamin, John Thomas and Robert ran the business together after 1899.

That's all so far, all from my armchair, hooray for 'Lancashire BMD'
