Joseph Blisset(t) married Maria Annetts on 1 Nov 1834 in Chilton, Berkshire. They had 4 children that I can find.
Frederick baptised Chilton 14 Oct 1832 (although 2 years before marriage, transcription gives surname as Blissett as if Joseph and Maria were married),
Caroline bapt Chilton 12 July 1843 (age 7)
Marian reg as Female Blissett Q1 1839 (appears as N K on 1841 census. Piece 14, Book 3, Folio 6, Page 6)
Joseph is transported for life on 21 Feb 1843.
There is a baptism of a Joseph Blissett illeg son of Maria at Chilton on 29 Dec 1844
In 1851 Maria (described as widow) is with Caroline (recorded as Catherine), Marian and Frederick in Chilton.
Frederick is with Joseph and Sarah Hatto and their family, described as nephew, but is really 1st cousin to Sarah Hatto nee Annetts.
I think Caroline married William Owen in Reading district in Q1 1861. On the 1861 census they are with a daughter Georgeana Owen born Chilton age 4 . Piece:746, Folio: 5, Page: 3
I can't find Georgeana's birth reg either as Owen or as Blissett.
In 1871 Caroline has two more children (Sarah and Albert) and in 1881 more children- Margaret and Katie. I can probably trace this family further
I have Joseph jnr from 1871 to 1891 with much older wife Deborah, but no children
But can anyone find any trace of Frederick, Marian and their mother Maria after 1851. I had though Maria may have married William Murrell Q3 1851, but have been unable to find either of them in 1861
