HEAVILY EDITED 15/2/24 am
Yes, I've really hunted for the whole family but can't find anyone else researching the family, no public trees or links to other researchers. I can only find the family of George born Lambeth, Clarissa born Shoreditch, daughter Clarissa b ca 1835, daughter Sarah Ann b ca 1836 & Joseph aged 9 in one census as well - 1851 HO107 Piece 1534 Folio 537 Page 24 although Clarissa may be on 1841 HO107 Piece 709 Folio 12 Page 17 and going on through censuses till 1891 [widowed by 1861] when she is living at 12 Red Lion Court aged 85 with a granddaughter Clarissa aged 23 born St Lukes. Clarissa snr dies in 1898 aged 93.
Deaths Sep 1898
Jackson Clarissa 93 Whitechapel 1c 188
I realise now that there will be no descendants of Joseph Blandford Jackson and Sarah Ann Gamble as Sarah died 1869, Joseph 1873, their daughters Sarah Ann & Elizabeth Clarissa never married and son Joseph died in 1874.
So looking for descendants of George Jackson b ca 1785 & Clarissa Clark b ca 1806 married 12 Mar 1832 @ St Stephen Coleman St. Obviously one granddaughter Clarissa Jackson b ca 1868 though I haven't yet found her birth and MMN. The only one I can find born in St Lukes is
JACKSON, CLARISSA WOOD
GRO Reference: 1845 M Quarter in SAINT LUKE MIDDLESEX Volume 02 Page 333 but this would make her 45 in 1891 and I think she is daughter of Robert Jackson and Frances Ann Wood.
