I have been working on the Blower and Sedgwick families and have sorted them out (somewhat). The one consistency has been that virtually all marriage, birth, and death registrations have been in Lichfield, Staffs.
Blower Family:
1837 - Joseph Blower m. Mary Edwards, St Michael, Lichfield (familysearch.org),
1837 - daughter Emma Blower born (4qua/17/44),

1841 - Joseph Bloore (sp), wife Mary, daughter Emma and son William living at Harehurst Hill, (H0107/1008/4-45/17),
1842 - daughter Mary Blower born (4qua/17/63),
1845 - daughter Sarah Blower born (2qua/17/70),
1846 - son James Blower born (4qua/17/66),
1847 - wife Mary Blower dies (4qua/17/45).

1841 - William & Martha Sedgwick possibly in Liverpool (H0107/566/13),

1845 - husband William Sedgwick dies (3qua/17/45),
1846 - daughter Mary Sedgwick (3qua/17/83) or Mary Anne Sedgwick (2qua/17/137 - Stafford, Staffs) born.
1850 - Joseph Blower m. Martha Sedgwick (2qua/17/105),
1851 - Joseph Blower, wife Martha, combined family of son William, daughters Mary, Sarah, Mary Ann and Emma (Emily) living at Harehurst, St. Michael (H0107/2014/462/26-27),
1851 - daughter Eliza Blower born (3qua/17/78),
1853 - son Thomas Stevenson Blower born (1qua/6B/290),
1859 - wife Martha Blower dies (4qua/6B/223).
1861 - Joseph Blower (widower), oldest daughter Emma (born in Shenstone), James, Eliza, and Thomas Stevenson Blower living at Wall, Staffs. (RG09/1974/73/11).
1871 - Joseph Blower, wife Lucy, and granddaughter Mary, 7 (b. 1864) living at Wall Lane, Lichfield (RG10/2915/95/10).
1881 - Joseph Blower (widower), and granddaughter Mary, 17 living at Church Cottages, Lichfield (RG11/2775/47/12).
Sorry to do such a long post but perhaps the information will be useful to someone else. It was interesting but a little disappointing since the Mary/Mary Anns are still confused and there is no George Blower, coachman.
Still stumped
