Sorry it has taken me so long to get back to you but my great grandmother as Annie Isobel Hicks(born 1880), her father was William Hicks (born 1839) married to Margaret Southam (nee Jessup) (1868), his father was John James married to Margaret Brain, (1834)his father was James married to Margaret.
My G grandmother's siblings were; James - 1869 Margaret- 1870 Jospeh Henry - 1875 Florence - 1874 Alice Eulalie - 1872 Mary Jane - 1878 Annie Isobel - 1880 William James - 1882 Richard John - 1884
My GG grandfathers (William) siblings were; Henry Thomas - 1836 William - 1839 Richard - 1840 George - 1846 Deborah - 1848 James - 1850 Alice - 1852 Anne - 1853 Mary Jane - 1855 Charles - 1857 Hamilton - 1859 Thomas - 1857 Margaret Minnie 1862
I have got a lot of my information from my granny who is still alive and more specific dates from the Church of Later Day Saints Web Site.
I have hit a wall the same as you, as I cannot find out whoJohn James Hicks' parents wedding dates or maiden name information.
